on this subject, apart from the fact I don't have
/usr/share/timezone/Australia/Sydney
or even /usr/share/timezone

more pertinent is that my ntpd is not really keeping my clock updated

what do I need to do to see what I'm missing:

ntp is network time protocol.  It keeps UTC in sync not daylight savings
which is offset from UTC.

ntpd will only reset the clock by a few microseconds.  you start this
with ntpdate  which will force the update then ntpd will keep
this on track.  You might want this in oyur boot sequence like ubuntu
does.

Re: [SLUG] Timezone/Daylight savings query.

2005-12-30 Thread Howard Lowndes 
The last time the time zone changed was for the SY Olympics and a new 
modified zone file was supplied (at least from RH).


With FC the ntpd daemon handles the time adjustment at boot and if there 
is a /etc/ntp/step-tickers file with a ntpd server in it then a sync 
gets done to that server as part of starting the ntpd daemon.


At the moment, according to the zone files, DST ends on Apr 2 in all 
states that have DST, which strikes me as being a week later than normal.

man ntpdate

try the -b and the -u options, the -s option merely changes where the 
logging happens.


-b forces the time to be altered instead of slewed
-u uses unpriv src ports, but I still think you should be checking your 
firewalling.

If someone don't file it, then I will do it. I think I should also
look at getting apple notified too, although I think a friend will be

It's probably an upstream issue.  The tzdata file
which distributions package is at
  ftp://elsie.nci.nih.gov/pub/
in the tzdata*.tar.gz files.

Proposed alterations should be e-mailed to
  tz at elsie dot nci dot hih dot gov
with a link to the authoritative source of the change
(in your case, to the regulation of the NSW government).

I've just downloaded the tzdata2005r.tar.gz file and it
says in part

# Rule  NAMEFROMTO  TYPEIN  ON  AT  SAVELETTER/S
...
RuleAN  2001max -   Oct lastSun 2:00s   1:00-
RuleAN  2006only-   Apr Sun>=1  2:00s   0   -
RuleAN  2007max -   Mar lastSun 2:00s   0   -

Which suggests to me that the daylight savings time change
for 2006 has already been incorporated.

Also note that there was a leap second this year. So your
NTP-based time will be 1s wrong if you have a tzdata earlier
than 2005k.

So drop in a bug with your distribution to update the tzdata
package from upstream.  I do wish that distros would
update the tzdata package immediately prior to issuing a
new version, but they seem to be needed to be prodded.

From what I understand of things, Unix timezone data has nothing to do
with leap seconds.  NTP, on the other hand, does - so any NTP-based
system will correctly adjust for leap seconds (effectively shifting
the epoch by 1 second each time).
