Time Zone

[Robert Dege]

Somehow, when I installed RedHat 7.2, my TimeZone was set to GMT,
instead of EST (or America/NewYork in /etc/sysconfig/clock).  I have
since corrected the file, but even upon reboot, `date` still reports it
as GMT-5, and ntp resets my time accordingly.

I see that /sbin/hwclock can be used to alter the time, but I don't know
how to reset the zone.  Any help is appreciated.

My guess, and it is just a guess is that named cannot find any time zone
information since it it chrooted.  Can you give it a copy of /etc/locatime or

named is logging in the wrong time zone

[Dan Horth]

Hi - I set up our named server on one of our test servers in a chroot 
jail over the weekend in our ongoing effort to tighten security as 
much as possible, and have noticed a strange thing - in that named is 
logging all it's info to the syslog at a different time to the rest 
of the stuff being logged to the syslog.

as far as I can tell named is logging it's entries in UTC while the 
rest of the entries are in the local (UTC + 11) timezone

ie:

Oct 30 11:50:41 guineapig sshd[408]: Generating new 768 bit RSA key.
Oct 30 11:50:41 guineapig sshd[408]: RSA key generation complete.
Oct 30 00:51:21 guineapig named[21198]: ns_resp: query(yahoo.co.uk) 
NS points to CNAME

Oct 30 03:06:10 guineapig named[21198]: Cleaned cache of 90 RRsets

This only started happening since I set up the chroot jail - I'm 
guessing it has to do with the /chroothome/bind/dev/log device node 
thingy I had to set up as part of the chrooting process:

srw-rw-rw-   1 bindbind0 Oct 29 22:54 /chroothome/bind/dev/log

and this entry in /etc/rc.d/init.d/syslog to start syslog paying 
attention to the new log device node thing:

daemon syslogd -m 0 -a /chroothome/bind/dev/log

does anyone know what might be going on here?

In 5.2 is a symlink to a binary file, so if you run "file localtime" it
does show that it is a binary file.  However, it still is a
symlink.  Just to clarify.

Easist way is to run Linuxconf as root, go down to the
bottom of the list and go into time and date.  select the
region from the dropdown.
It is what I do anyway.

BTW mad manners to send html to most mailing lists
(including this one)

Hope this helps,

Not running 6.2 here, but if I go to /etc and run "ls -l" it shows that
the file localtime is actually a symnbolic link that should be pretty much
self-explanatory.  I have a feeling if you set up a link to the correct

No, that one gets fixed by timeconfig.  I've got some extracts from
/var/log/messages that say where things go wrong.  Unfortunately that
doesn't tell me what to fix.

The first set comes from bootup:

Nov 23 05:33:21 collatz atd: atd startup succeeded
Nov 23 07:33:06 collatz rc.sysinit: Loading default keymap succeeded 
Nov 23 07:33:06 collatz rc.sysinit: Setting default font succeeded 
...
Nov 23 07:33:14 collatz fsck: /dev/hda6: clean, 9181/132600 files, 113856/529168
 blocks 
Nov 23 07:33:14 collatz rc.sysinit: Checking filesystems succeeded 
Nov 23 07:33:16 collatz rc.sysinit: Mounting local filesystems succeeded 
Nov 23 07:33:16 collatz rc.sysinit: Turning on user and group quotas for local f
ilesystems succeeded 
Nov 23 05:33:19 collatz date: Tue Nov 23 05:33:19 SAST 1999 
Nov 23 05:33:19 collatz rc.sysinit: Setting clock : Tue Nov 23 05:33:19 SAST 199
9 succeeded 
Nov 23 05:33:19 collatz rc.sysinit: Enabling swap space succeeded 
Nov 23 05:33:19 collatz init: Entering runlevel: 3 

So when atd starts, it gets information that time is GMT and resets system
time.  Then it stays there for a while, until rc.sysinit obviously working
off /etc/sysconfig/clock as it should, sets the clock back to the hardware 
reading.  

The next extract comes from a point when apmd made my screen go blank:

Nov 23 09:37:16 collatz PAM_pwdb[285]: (login) session opened for user dirk by (
uid=0)
Nov 23 12:47:28 collatz apmd[122]: Resume after 02:16:53 (65% unknown)
Nov 23 13:01:19 collatz sudo: dirk : TTY=pts/0 ; PWD=/home/dirk/kantoor/navo
rs/artikels/gauss-survey ; USER=root ; COMMAND=/sbin/hwclock --hctosys 
Nov 23 11:02:26 collatz sudo: dirk : TTY=tty1 ; PWD=/home/dirk/kantoor/navor
s/artikels/gauss-survey ; USER=root ; COMMAND=/usr/bin/less /var/log/messages 

I had been working for about an hour and then went for tea.  Coming back,
I reactivated the screen, discovered that GMT had reasserted itself, and
manually reset the system clock.

These two-hour jumps to and fro can't be good for the integrity of the
system.

IMHO the above behaviour is a bug, caused by some old code somewhere
that dates back to the days before we had /etc/sysconfig.  But where
does that code get its information?

Time zone configuration

[Dirk Laurie]

When I installed RH6.0, I thought that keeping the hardware clock
on GMT was the proper thing to do.  Unfortunately it does not make
for peaceful coexistence with 98, which also has its little corner
of the box.  Now I can't get back to local time.  I've run timeconfig
again, deselected the "Clock set to GMT" box, but each time I boot
up (this is a notebook computer) it adds the difference to the
hardware clock.  I can type "hwclock --hctosys" and then it's OK.
So somewhere in the boot-up scripts the GMT must have got hardcoded
at installation time.  Any idea where?

This may seem trivial and well, it is, but I cannot seem to set the system

Looking at 2.0.32 this is what I see.
The kernel keeps track of the local time, which is set bye the
system call settimeofday.

When a fat filesystem date is converted to a unix date minuteswest minutes are added
to the time.

When a unix date is converted to a fat filesystem date minuteswest are subtracted
from the current time.

So it appears that the linux kernel has the wrong idea of the local time zone, a la
minueswest.

As I understand it the first call to settimeofday that includes time zone 
information must have the correct time zone set, to give linux the proper
system time (from the real time clock).  So the time zone got set
right at least once.  
For machines with clocks in UTC the first call to settimeofday with a
time zone specified must not set a time zone offset (minuteswest).

All further calls to settimeofday (with a time zone specified) just
affect the kernel's notion of local time.

So a call to settimeofday with an appropriate time zone value should
fix the problem.  Why this doesn't happen automatically I don't know.

I hope this helps,
Eric

Re: strange time zone behaviour by linux on windoze partition

[Dave Mielke]

Have you checked "/etc/sysconfig/clock" to insure that "UTC" is "false"?

strange time zone behaviour by linux on windoze partition

[Tony Nugent]

System: i386 RedHat 5.1 (glibc6)

I have not seen this problem myself, but I am passing this on as I am the
linux support person here at USQ.  This is what has been described to me,
and I haven't a clue as to why this is happening.  However, I suspect that
it could be a glibc issue...

When linux boots up and uses the system time, it all looks ok.  We are
GMT+10 hours here (Queensland Australia), and the bios clock is set at the
local time.  /etc/localtime is a symlink pointing to the correct
/usr/share/zoneinfo/ file.

Write a file to a vfat-mounted dos partition with linux and the timestamps
look good - the correct (current) time as would be expected.  (Of course,
same for timestamps on new files on the linux filesystem).

Boot into windows and the timestamps on any of these files are 10 hours
behind!

Create new files with the current timestamp with windose and all looks
good.  But boot into linux and look at those files -- they are 10 hours
ahead!  (Which means thay can be set for a time in the future).

This is obviously a problem related to the local time difference, but what
is going on?

Is windows at fault, or linux?  Or have we just discovered the secrets of a
time-travel machine?? :-)

Thanks for any clues as to what could be going on and how to prevent this
from happening.

This querkiness is totally screwing up some scripts that are designed to
use file timestamps to keep in sync files that need to be kept on both
partitions.

Many thanks for any help.

Cheers .
