News for the tz database
+Release 2015f - 2015-08-10 18:06:56 -0700
+
+ Changes affecting future time stamps
+
+ North Korea switches to +0830 on 2015-08-15. (Thanks to Steffen Thorsen.)
+ The abbreviation remains "KST". (Thanks to Robert Elz.)
+
+ Uruguay no longer observes DST. (Thanks to Steffen Thorsen
+ and Pablo Camargo.)
+
+ Changes affecting past and future time stamps
+
+ Moldova starts and ends DST at 00:00 UTC, not at 01:00 UTC.
+ (Thanks to Roman Tudos.)
+
+ Changes affecting data format and code
+
+ zic's '-y YEARISTYPE' option is no longer documented. The TYPE
+ field of a Rule line should now be '-'; the old values 'even',
+ 'odd', 'uspres', 'nonpres', 'nonuspres' were already undocumented.
+ Although the implementation has not changed, these features do not
+ work in the default installation, they are not used in the data,
+ and they are now considered obsolescent.
+
+ zic now checks that two rules don't take effect at the same time.
+ (Thanks to Jon Skeet and Arthur David Olson.) Constraints on
+ simultaneity are now documented.
+
+ The two characters '%z' in a zone format now stand for the UTC
+ offset, e.g., '-07' for seven hours behind UTC and '+0530' for
+ five hours and thirty minutes ahead. This better supports time
+ zone abbreviations conforming to POSIX.1-2001 and later.
+
+ Changes affecting installed data files
+
+ Comments for America/Halifax and America/Glace_Bay have been improved.
+ (Thanks to Brian Inglis.)
+
+ Data entries have been simplified for Atlantic/Canary, Europe/Simferopol,
+ Europe/Sofia, and Europe/Tallinn. This yields slightly smaller
+ installed data files for Europe/Simferopol and Europe/Tallinn.
+ It does not affect timestamps. (Thanks to Howard Hinnant.)
+
+ Changes affecting code
+
+ zdump and zic no longer warn about valid time zone abbreviations
+ like '-05'.
+
+ Some Visual Studio 2013 warnings have been suppressed.
+ (Thanks to Kees Dekker.)
+
+ 'date' no longer sets the time of day and its -a, -d, -n and -t
+ options have been removed. Long obsolescent, the implementation
+ of these features had porting problems. Builders no longer need
+ to configure HAVE_ADJTIME, HAVE_SETTIMEOFDAY, or HAVE_UTMPX_H.
+ (Thanks to Kees Dekker for pointing out the problem.)
+
+ Changes affecting documentation
+
+ The Theory file mentions naming issues earlier, as these seem to be
+ poorly publicized (thanks to Gilmore Davidson for reporting the problem).
+
+ tz-link.htm mentions Time Zone Database Parser (thanks to Howard Hinnant).
+
+ Mention that Herbert Samuel introduced the term "Summer Time".
+
+
+Release 2015e - 2015-06-13 10:56:02 -0700
+
+ Changes affecting future time stamps
+
+ Morocco will suspend DST from 2015-06-14 03:00 through 2015-07-19 02:00,
+ not 06-13 and 07-18 as we had guessed. (Thanks to Milamber.)
+
+ Assume Cayman Islands will observe DST starting next year, using US rules.
+ Although it isn't guaranteed, it is the most likely.
+
+ Changes affecting data format
+
+ The file 'iso3166.tab' now uses UTF-8, so that its entries can better
+ spell the names of Åland Islands, Côte d'Ivoire, and Réunion.
+
+ Changes affecting code
+
+ When displaying data, tzselect converts it to the current locale's
+ encoding if the iconv command works. (Problem reported by random832.)
+
+ tzselect no longer mishandles Dominica, fixing a bug introduced
+ in Release 2014f. (Problem reported by Owen Leibman.)
+
+ zic -l no longer fails when compiled with -DTZDEFAULT=\"/etc/localtime\".
+ This fixes a bug introduced in Release 2014f.
+ (Problem reported by Leonardo Chiquitto.)
+
+
+Release 2015d - 2015-04-24 08:09:46 -0700
+
+ Changes affecting future time stamps
+
+ Egypt will not observe DST in 2015 and will consider canceling it
+ permanently. For now, assume no DST indefinitely.
+ (Thanks to Ahmed Nazmy and Tim Parenti.)
+
+ Changes affecting past time stamps
+
+ America/Whitehorse switched from UTC-9 to UTC-8 on 1967-05-28, not
+ 1966-07-01. Also, Yukon's time zone history is documented better.
+ (Thanks to Brian Inglis and Dennis Ferguson.)
+
+ Change affecting past and future time zone abbreviations
+
+ The abbreviations for Hawaii-Aleutian standard and daylight times
+ have been changed from HAST/HADT to HST/HDT, as per US Government
+ Printing Office style. This affects only America/Adak since 1983,
+ as America/Honolulu was already using the new style.
+
+ Changes affecting code
+
+ zic has some minor performance improvements.
+
+
+Release 2015c - 2015-04-11 08:55:55 -0700
+
+ Changes affecting future time stamps
+
+ Egypt's spring-forward transition is at 24:00 on April's last Thursday,
+ not 00:00 on April's last Friday. 2015's transition will therefore be on
+ Thursday, April 30 at 24:00, not Friday, April 24 at 00:00. Similar fixes
+ apply to 2026, 2037, 2043, etc. (Thanks to Steffen Thorsen.)
+
+ Changes affecting past time stamps
+
+ The following changes affect some pre-1991 Chile-related time stamps
+ in America/Santiago, Antarctica/Palmer, and Pacific/Easter.
+
+ The 1910 transition was January 10, not January 1.
+
+ The 1918 transition was September 10, not September 1.
+
+ The UTC-4 time observed from 1932 to 1942 is now considered to be
+ standard time, not year-round DST.
+
+ Santiago observed DST (UTC-3) from 1946-07-15 through 1946-08-31,
+ then reverted to standard time, then switched its time zone to
+ UTC-5 on 1947-04-01.
+
+ Assume transitions before 1968 were at 00:00, since we have no data
+ saying otherwise.
+
+ The spring 1988 transition was 1988-10-09, not 1988-10-02.
+ The fall 1990 transition was 1990-03-11, not 1990-03-18.
+
+ Assume no UTC offset change for Pacific/Easter on 1890-01-01,
+ and omit all transitions on Pacific/Easter from 1942 through 1946
+ since we have no data suggesting that they existed.
+
+ One more zone has been turned into a link, as it differed
+ from an existing zone only for older time stamps. As usual,
+ this change affects UTC offsets in pre-1970 time stamps only.
+ The zone's old contents have been moved to the 'backzone' file.
+ The affected zone is America/Montreal.
+
+ Changes affecting commentary
+
+ Mention the TZUpdater tool.
+
+ Mention "The Time Now". (Thanks to Brandon Ramsey.)

------ Time and date functions -----
-These time and date functions are upwards compatible with those of POSIX,
-an international standard for UNIX-like systems.
-As of this writing, the current edition of POSIX is:
-
- The Open Group Base Specifications Issue 7
- IEEE Std 1003.1, 2013 Edition
- <http://pubs.opengroup.org/onlinepubs/9699919799/>
-
-POSIX has the following properties and limitations.
+----- Scope of the tz database -----
-* In POSIX, time display in a process is controlled by the
- environment variable TZ. Unfortunately, the POSIX TZ string takes
- a form that is hard to describe and is error-prone in practice.
- Also, POSIX TZ strings can't deal with other (for example, Israeli)
- daylight saving time rules, or situations where more than two
- time zone abbreviations are used in an area.
+The tz database attempts to record the history and predicted future of
+all computer-based clocks that track civil time. To represent this
+data, the world is partitioned into regions whose clocks all agree
+about time stamps that occur after the somewhat-arbitrary cutoff point
+of the POSIX Epoch (1970-01-01 00:00:00 UTC). For each such region,
+the database records all known clock transitions, and labels the region
+with a notable location. Although 1970 is a somewhat-arbitrary
+cutoff, there are significant challenges to moving the cutoff earlier
+even by a decade or two, due to the wide variety of local practices
+before computer timekeeping became prevalent.
- The POSIX TZ string takes the following form:
+Clock transitions before 1970 are recorded for each such location,
+because most systems support time stamps before 1970 and could
+misbehave if data entries were omitted for pre-1970 transitions.
+However, the database is not designed for and does not suffice for
+applications requiring accurate handling of all past times everywhere,
+as it would take far too much effort and guesswork to record all
+details of pre-1970 civil timekeeping.
- stdoffset[dst[offset][,date[/time],date[/time]]]
+As described below, reference source code for using the tz database is
+also available. The tz code is upwards compatible with POSIX, an
+international standard for UNIX-like systems. As of this writing, the
+current edition of POSIX is:
- where:
+ The Open Group Base Specifications Issue 7
+ IEEE Std 1003.1, 2013 Edition
+ <http://pubs.opengroup.org/onlinepubs/9699919799/>
- std and dst
- are 3 or more characters specifying the standard
- and daylight saving time (DST) zone names.
- Starting with POSIX.1-2001, std and dst may also be
- in a quoted form like "<UTC+10>"; this allows
- "+" and "-" in the names.
- offset
- is of the form '[+-]hh:[mm[:ss]]' and specifies the
- offset west of UT. 'hh' may be a single digit; 0<=hh<=24.
- The default DST offset is one hour ahead of standard time.
- date[/time],date[/time]
- specifies the beginning and end of DST. If this is absent,
- the system supplies its own rules for DST, and these can
- differ from year to year; typically US DST rules are used.
- time
- takes the form 'hh:[mm[:ss]]' and defaults to 02:00.
- This is the same format as the offset, except that a
- leading '+' or '-' is not allowed.
- date
- takes one of the following forms:
- Jn (1<=n<=365)
- origin-1 day number not counting February 29
- n (0<=n<=365)
- origin-0 day number counting February 29 if present
- Mm.n.d (0[Sunday]<=d<=6[Saturday], 1<=n<=5, 1<=m<=12)
- for the dth day of week n of month m of the year,
- where week 1 is the first week in which day d appears,
- and '5' stands for the last week in which day d appears
- (which may be either the 4th or 5th week).
- Typically, this is the only useful form;
- the n and Jn forms are rarely used.
- Here is an example POSIX TZ string, for US Pacific time using rules
- appropriate from 1987 through 2006:
- TZ='PST8PDT,M4.1.0/02:00,M10.5.0/02:00'
+----- Names of time zone rules -----
- This POSIX TZ string is hard to remember, and mishandles time stamps
- before 1987 and after 2006. With this package you can use this
- instead:
+Each of the database's time zone rules has a unique name.
+Inexperienced users are not expected to select these names unaided.
+Distributors should provide documentation and/or a simple selection
+interface that explains the names; for one example, see the 'tzselect'
+program in the tz code. The Unicode Common Locale Data Repository
+<http://cldr.unicode.org/> contains data that may be useful for other
+selection interfaces.
- TZ='America/Los_Angeles'
+The time zone rule naming conventions attempt to strike a balance
+among the following goals:
-* POSIX does not define the exact meaning of TZ values like "EST5EDT".
- Typically the current US DST rules are used to interpret such values,
- but this means that the US DST rules are compiled into each program
- that does time conversion. This means that when US time conversion
- rules change (as in the United States in 1987), all programs that
- do time conversion must be recompiled to ensure proper results.
+ * Uniquely identify every region where clocks have agreed since 1970.
+ This is essential for the intended use: static clocks keeping local
+ civil time.
+
+ * Indicate to experts where that region is.
+
+ * Be robust in the presence of political changes. For example, names
+ of countries are ordinarily not used, to avoid incompatibilities
+ when countries change their name (e.g. Zaire->Congo) or when
+ locations change countries (e.g. Hong Kong from UK colony to
+ China).
-* In POSIX, there's no tamper-proof way for a process to learn the
- system's best idea of local wall clock. (This is important for
- applications that an administrator wants used only at certain times -
- without regard to whether the user has fiddled the "TZ" environment
- variable. While an administrator can "do everything in UTC" to get
- around the problem, doing so is inconvenient and precludes handling
- daylight saving time shifts - as might be required to limit phone
- calls to off-peak hours.)
+ * Be portable to a wide variety of implementations.
-* POSIX requires that systems ignore leap seconds.
+ * Use a consistent naming conventions over the entire world.
-* The tz code attempts to support all the time_t implementations
- allowed by POSIX. The time_t type represents a nonnegative count of
- seconds since 1970-01-01 00:00:00 UTC, ignoring leap seconds.
- In practice, time_t is usually a signed 64- or 32-bit integer; 32-bit
- signed time_t values stop working after 2038-01-19 03:14:07 UTC, so
- new implementations these days typically use a signed 64-bit integer.
- Unsigned 32-bit integers are used on one or two platforms,
- and 36-bit and 40-bit integers are also used occasionally.
- Although earlier POSIX versions allowed time_t to be a
- floating-point type, this was not supported by any practical
- systems, and POSIX.1-2013 and the tz code both require time_t
- to be an integer type.
+Names normally have the form AREA/LOCATION, where AREA is the name
+of a continent or ocean, and LOCATION is the name of a specific
+location within that region. North and South America share the same
+area, 'America'. Typical names are 'Africa/Cairo', 'America/New_York',
+and 'Pacific/Honolulu'.
-These are the extensions that have been made to the POSIX functions:
+Here are the general rules used for choosing location names,
+in decreasing order of importance:
-* The "TZ" environment variable is used in generating the name of a file
- from which time zone information is read (or is interpreted a la
- POSIX); "TZ" is no longer constrained to be a three-letter time zone
- name followed by a number of hours and an optional three-letter
- daylight time zone name. The daylight saving time rules to be used
- for a particular time zone are encoded in the time zone file;
- the format of the file allows U.S., Australian, and other rules to be
- encoded, and allows for situations where more than two time zone
- abbreviations are used.
+ Use only valid POSIX file name components (i.e., the parts of
+ names other than '/'). Do not use the file name
+ components '.' and '..'. Within a file name component,

+ characters or start with '-'. E.g., prefer 'Brunei'
+ to 'Bandar_Seri_Begawan'. Exceptions: see the discussion
+ of legacy names below.
+ A name must not be empty, or contain '//', or start or end with '/'.
+ Do not use names that differ only in case. Although the reference
+ implementation is case-sensitive, some other implementations
+ are not, and they would mishandle names differing only in case.
+ If one name A is an initial prefix of another name AB (ignoring case),
+ then B must not start with '/', as a regular file cannot have
+ the same name as a directory in POSIX. For example,
+ 'America/New_York' precludes 'America/New_York/Bronx'.
+ Uninhabited regions like the North Pole and Bouvet Island
+ do not need locations, since local time is not defined there.
+ There should typically be at least one name for each ISO 3166-1
+ officially assigned two-letter code for an inhabited country

+ If all the clocks in a region have agreed since 1970,
+ don't bother to include more than one location
+ even if subregions' clocks disagreed before 1970.
+ Otherwise these tables would become annoyingly large.
+ If a name is ambiguous, use a less ambiguous alternative;
+ e.g. many cities are named San José and Georgetown, so
+ prefer 'Costa_Rica' to 'San_Jose' and 'Guyana' to 'Georgetown'.
+ Keep locations compact. Use cities or small islands, not countries
+ or regions, so that any future time zone changes do not split
+ locations into different time zones. E.g. prefer 'Paris'
+ to 'France', since France has had multiple time zones.
+ Use mainstream English spelling, e.g. prefer 'Rome' to 'Roma', and
+ prefer 'Athens' to the Greek 'Αθήνα' or the Romanized 'Athína'.
+ The POSIX file name restrictions encourage this rule.
+ Use the most populous among locations in a zone,
+ e.g. prefer 'Shanghai' to 'Beijing'. Among locations with
+ similar populations, pick the best-known location,
+ e.g. prefer 'Rome' to 'Milan'.
+ Use the singular form, e.g. prefer 'Canary' to 'Canaries'.
+ Omit common suffixes like '_Islands' and '_City', unless that
+ would lead to ambiguity. E.g. prefer 'Cayman' to
+ 'Cayman_Islands' and 'Guatemala' to 'Guatemala_City',
+ but prefer 'Mexico_City' to 'Mexico' because the country
+ of Mexico has several time zones.
+ Use '_' to represent a space.
+ Omit '.' from abbreviations in names, e.g. prefer 'St_Helena'
+ to 'St._Helena'.
+ Do not change established names if they only marginally
+ violate the above rules. For example, don't change
+ the existing name 'Rome' to 'Milan' merely because
+ Milan's population has grown to be somewhat greater
+ than Rome's.
+ If a name is changed, put its old spelling in the 'backward' file.

+Older versions of this package used a different naming scheme,
+and these older names are still supported.
+See the file 'backward' for most of these older names

- needed. (These variables are defined and set by "tzset"; however, their
- values will not be used by "localtime.")
+Older versions of this package defined legacy names that are
+incompatible with the first rule of location names, but which are
+still supported. These legacy names are mostly defined in the file
+'etcetera'. Also, the file 'backward' defines the legacy names
+'GMT0', 'GMT-0', 'GMT+0' and 'Canada/East-Saskatchewan', and the file

+----- Time zone abbreviations -----
-* These functions can account for leap seconds, thanks to Bradley White.
+When this package is installed, it generates time zone abbreviations
+like 'EST' to be compatible with human tradition and POSIX.
+Here are the general rules used for choosing time zone abbreviations,
+in decreasing order of importance:
-Points of interest to folks with other systems:
+ Use abbreviations that consist of three or more ASCII letters.
+ Previous editions of this database also used characters like
+ ' ' and '?', but these characters have a special meaning to
+ the shell and cause commands like
+ set `date`
+ to have unexpected effects.
+ Previous editions of this rule required upper-case letters,
+ but the Congressman who introduced Chamorro Standard Time
+ preferred "ChST", so the rule has been relaxed.
-* This package is already part of many POSIX-compliant hosts,
- including BSD, HP, Linux, Network Appliance, SCO, SGI, and Sun.
- On such hosts, the primary use of this package
- is to update obsolete time zone rule tables.
- To do this, you may need to compile the time zone compiler
- 'zic' supplied with this package instead of using the system 'zic',
- since the format of zic's input changed slightly in late 1994,
- and many vendors still do not support the new input format.
+ This rule guarantees that all abbreviations could have
+ been specified by a POSIX TZ string. POSIX
+ requires at least three characters for an
+ abbreviation. POSIX through 2000 says that an abbreviation
+ cannot start with ':', and cannot contain ',', '-',
+ '+', NUL, or a digit. POSIX from 2001 on changes this
+ rule to say that an abbreviation can contain only '-', '+',
+ and alphanumeric characters from the portable character set
+ in the current locale. To be portable to both sets of
+ rules, an abbreviation must therefore use only ASCII
+ letters.
-* The UNIX Version 7 "timezone" function is not present in this package;
- it's impossible to reliably map timezone's arguments (a "minutes west
- of GMT" value and a "daylight saving time in effect" flag) to a
- time zone abbreviation, and we refuse to guess.
- Programs that in the past used the timezone function may now examine
- tzname[localtime(&clock)->tm_isdst] to learn the correct time
- zone abbreviation to use. Alternatively, use
- localtime(&clock)->tm_zone if this has been enabled.
+ Use abbreviations that are in common use among English-speakers,
+ e.g. 'EST' for Eastern Standard Time in North America.
+ We assume that applications translate them to other languages
+ as part of the normal localization process; for example,
+ a French application might translate 'EST' to 'HNE'.
-* The 4.2BSD gettimeofday function is not used in this package.
- This formerly let users obtain the current UTC offset and DST flag,
- but this functionality was removed in later versions of BSD.
+ For zones whose times are taken from a city's longitude, use the
+ traditional xMT notation, e.g. 'PMT' for Paris Mean Time.
+ The only name like this in current use is 'GMT'.
-* In SVR2, time conversion fails for near-minimum or near-maximum
- time_t values when doing conversions for places that don't use UT.
- This package takes care to do these conversions correctly.
+ Use 'LMT' for local mean time of locations before the introduction
+ of standard time; see "Scope of the tz database".
-The functions that are conditionally compiled if STD_INSPIRED is defined
-should, at this point, be looked on primarily as food for thought. They are
-not in any sense "standard compatible" - some are not, in fact, specified in
-*any* standard. They do, however, represent responses of various authors to
-standardization proposals.
+ If there is no common English abbreviation, use numeric offsets like
+ -05 and +0830 that are generated by zic's %z notation.
-Other time conversion proposals, in particular the one developed by folks at
-Hewlett Packard, offer a wider selection of functions that provide capabilities
-beyond those provided here. The absence of such functions from this package
-is not meant to discourage the development, standardization, or use of such
-functions. Rather, their absence reflects the decision to make this package
-contain valid extensions to POSIX, to ensure its broad acceptability. If
-more powerful time conversion functions can be standardized, so much the
-better.
+ [The remaining guidelines predate the introduction of %z.
+ They are problematic as they mean tz data entries invent
+ notation rather than record it. These guidelines are now
+ deprecated and the plan is to gradually move to %z for
+ inhabited locations and to "-00" for uninhabited locations.]
+ If there is no common English abbreviation, abbreviate the English
+ translation of the usual phrase used by native speakers.
+ If this is not available or is a phrase mentioning the country
+ (e.g. "Cape Verde Time"), then:
------ Scope of the tz database -----
+ When a country is identified with a single or principal zone,
+ append 'T' to the country's ISO code, e.g. 'CVT' for
+ Cape Verde Time. For summer time append 'ST';
+ for double summer time append 'DST'; etc.
+ Otherwise, take the first three letters of an English place
+ name identifying each zone and append 'T', 'ST', etc.
+ as before; e.g. 'VLAST' for VLAdivostok Summer Time.
-The tz database attempts to record the history and predicted future of
-all computer-based clocks that track civil time. To represent this
-data, the world is partitioned into regions whose clocks all agree
-about time stamps that occur after the somewhat-arbitrary cutoff point
-of the POSIX Epoch (1970-01-01 00:00:00 UTC). For each such region,
-the database records all known clock transitions, and labels the region
-with a notable location. Although 1970 is a somewhat-arbitrary
-cutoff, there are significant challenges to moving the cutoff earlier
-even by a decade or two, due to the wide variety of local practices
-before computer timekeeping became prevalent.
+ Use UT (with time zone abbreviation 'zzz') for locations while
+ uninhabited. The 'zzz' mnemonic is that these locations are,
+ in some sense, asleep.
-Clock transitions before 1970 are recorded for each such location,
-because most POSIX-compatible systems support negative time stamps and
-could misbehave if data entries were omitted for pre-1970 transitions.
-However, the database is not designed for and does not suffice for
-applications requiring accurate handling of all past times everywhere,
-as it would take far too much effort and guesswork to record all
-details of pre-1970 civil timekeeping.
+Application writers should note that these abbreviations are ambiguous
+in practice: e.g. 'CST' has a different meaning in China than
+it does in the United States. In new applications, it's often better
+to use numeric UT offsets like '-0600' instead of time zone
+abbreviations like 'CST'; this avoids the ambiguity.

-The time zone rule file naming conventions attempt to strike a balance
-among the following goals:
+The tz code contains time and date functions that are upwards
+compatible with those of POSIX.
+
+POSIX has the following properties and limitations.
+
+* In POSIX, time display in a process is controlled by the
+ environment variable TZ. Unfortunately, the POSIX TZ string takes
+ a form that is hard to describe and is error-prone in practice.
+ Also, POSIX TZ strings can't deal with other (for example, Israeli)
+ daylight saving time rules, or situations where more than two
+ time zone abbreviations are used in an area.
+
+ The POSIX TZ string takes the following form:
+
+ stdoffset[dst[offset][,date[/time],date[/time]]]
+
+ where:
+
+ std and dst
+ are 3 or more characters specifying the standard
+ and daylight saving time (DST) zone names.
+ Starting with POSIX.1-2001, std and dst may also be
+ in a quoted form like "<UTC+10>"; this allows
+ "+" and "-" in the names.
+ offset
+ is of the form '[+-]hh:[mm[:ss]]' and specifies the
+ offset west of UT. 'hh' may be a single digit; 0<=hh<=24.
+ The default DST offset is one hour ahead of standard time.
+ date[/time],date[/time]
+ specifies the beginning and end of DST. If this is absent,
+ the system supplies its own rules for DST, and these can
+ differ from year to year; typically US DST rules are used.
+ time
+ takes the form 'hh:[mm[:ss]]' and defaults to 02:00.
+ This is the same format as the offset, except that a
+ leading '+' or '-' is not allowed.
+ date
+ takes one of the following forms:
+ Jn (1<=n<=365)
+ origin-1 day number not counting February 29
+ n (0<=n<=365)
+ origin-0 day number counting February 29 if present
+ Mm.n.d (0[Sunday]<=d<=6[Saturday], 1<=n<=5, 1<=m<=12)
+ for the dth day of week n of month m of the year,
+ where week 1 is the first week in which day d appears,
+ and '5' stands for the last week in which day d appears
+ (which may be either the 4th or 5th week).
+ Typically, this is the only useful form;
+ the n and Jn forms are rarely used.
+
+ Here is an example POSIX TZ string, for US Pacific time using rules
+ appropriate from 1987 through 2006:
- * Uniquely identify every national region where clocks have all
- agreed since 1970. This is essential for the intended use: static
- clocks keeping local civil time.
-
- * Indicate to humans as to where that region is. This simplifies use.
-
- * Be robust in the presence of political changes. This reduces the
- number of updates and backward-compatibility hacks. For example,
- names of countries are ordinarily not used, to avoid
- incompatibilities when countries change their name
- (e.g. Zaire->Congo) or when locations change countries
- (e.g. Hong Kong from UK colony to China).
+ TZ='PST8PDT,M4.1.0/02:00,M10.5.0/02:00'
- * Be portable to a wide variety of implementations.
- This promotes use of the technology.
+ This POSIX TZ string is hard to remember, and mishandles time stamps
+ before 1987 and after 2006. With this package you can use this
+ instead:
- * Use a consistent naming convention over the entire world.
- This simplifies both use and maintenance.
+ TZ='America/Los_Angeles'
-This naming convention is not intended for use by inexperienced users
-to select TZ values by themselves (though they can of course examine
-and reuse existing settings). Distributors should provide
-documentation and/or a simple selection interface that explains the
-names; see the 'tzselect' program supplied with this distribution for
-one example.
+* POSIX does not define the exact meaning of TZ values like "EST5EDT".
+ Typically the current US DST rules are used to interpret such values,
+ but this means that the US DST rules are compiled into each program
+ that does time conversion. This means that when US time conversion
+ rules change (as in the United States in 1987), all programs that
+ do time conversion must be recompiled to ensure proper results.
-Names normally have the form AREA/LOCATION, where AREA is the name
-of a continent or ocean, and LOCATION is the name of a specific
-location within that region. North and South America share the same
-area, 'America'. Typical names are 'Africa/Cairo', 'America/New_York',
-and 'Pacific/Honolulu'.
+* In POSIX, there's no tamper-proof way for a process to learn the
+ system's best idea of local wall clock. (This is important for
+ applications that an administrator wants used only at certain times -
+ without regard to whether the user has fiddled the "TZ" environment
+ variable. While an administrator can "do everything in UTC" to get
+ around the problem, doing so is inconvenient and precludes handling
+ daylight saving time shifts - as might be required to limit phone
+ calls to off-peak hours.)
-Here are the general rules used for choosing location names,
-in decreasing order of importance:
+* POSIX requires that systems ignore leap seconds.
- Use only valid POSIX file name components (i.e., the parts of
- names other than '/'). Do not use the file name
- components '.' and '..'. Within a file name component,
- use only ASCII letters, '.', '-' and '_'. Do not use
- digits, as that might create an ambiguity with POSIX
- TZ strings. A file name component must not exceed 14

- If a name is changed, put its old spelling in the 'backward' file.
- This means old spellings will continue to work.
+* The tz code attempts to support all the time_t implementations
+ allowed by POSIX. The time_t type represents a nonnegative count of
+ seconds since 1970-01-01 00:00:00 UTC, ignoring leap seconds.
+ In practice, time_t is usually a signed 64- or 32-bit integer; 32-bit
+ signed time_t values stop working after 2038-01-19 03:14:07 UTC, so
+ new implementations these days typically use a signed 64-bit integer.
+ Unsigned 32-bit integers are used on one or two platforms,
+ and 36-bit and 40-bit integers are also used occasionally.
+ Although earlier POSIX versions allowed time_t to be a
+ floating-point type, this was not supported by any practical
+ systems, and POSIX.1-2013 and the tz code both require time_t
+ to be an integer type.

+* The "TZ" environment variable is used in generating the name of a file
+ from which time zone information is read (or is interpreted a la
+ POSIX); "TZ" is no longer constrained to be a three-letter time zone
+ name followed by a number of hours and an optional three-letter
+ daylight time zone name. The daylight saving time rules to be used
+ for a particular time zone are encoded in the time zone file;
+ the format of the file allows U.S., Australian, and other rules to be
+ encoded, and allows for situations where more than two time zone
+ abbreviations are used.

+ zone abbreviation to use. Alternatively, use
+ localtime(&clock)->tm_zone if this has been enabled.
- When a country is identified with a single or principal zone,
- append 'T' to the country's ISO code, e.g. 'CVT' for
- Cape Verde Time. For summer time append 'ST';
- for double summer time append 'DST'; etc.
- Otherwise, take the first three letters of an English place
- name identifying each zone and append 'T', 'ST', etc.
- as before; e.g. 'VLAST' for VLAdivostok Summer Time.
+* The 4.2BSD gettimeofday function is not used in this package.
+ This formerly let users obtain the current UTC offset and DST flag,
+ but this functionality was removed in later versions of BSD.
- Use 'LMT' for local mean time of locations before the introduction
- of standard time; see "Scope of the tz database".
+* In SVR2, time conversion fails for near-minimum or near-maximum
+ time_t values when doing conversions for places that don't use UT.
+ This package takes care to do these conversions correctly.
- Use UT (with time zone abbreviation 'zzz') for locations while
- uninhabited. The 'zzz' mnemonic is that these locations are,
- in some sense, asleep.
+The functions that are conditionally compiled if STD_INSPIRED is defined
+should, at this point, be looked on primarily as food for thought. They are
+not in any sense "standard compatible" - some are not, in fact, specified in
+*any* standard. They do, however, represent responses of various authors to
+standardization proposals.
-Application writers should note that these abbreviations are ambiguous
-in practice: e.g. 'CST' has a different meaning in China than
-it does in the United States. In new applications, it's often better
-to use numeric UT offsets like '-0600' instead of time zone
-abbreviations like 'CST'; this avoids the ambiguity.
+Other time conversion proposals, in particular the one developed by folks at
+Hewlett Packard, offer a wider selection of functions that provide capabilities
+beyond those provided here. The absence of such functions from this package
+is not meant to discourage the development, standardization, or use of such
+functions. Rather, their absence reflects the decision to make this package
+contain valid extensions to POSIX, to ensure its broad acceptability. If
+more powerful time conversion functions can be standardized, so much the
+better.
