Olympic Daylight Savings Time...

Olympic Daylight Savings Time...

Post by William Charle » Wed, 30 Aug 2000 07:35:25



Folks,

We just flipped daylight savings time two months early in preparation
for the Olympics.

Sun's zonefino patches seem to have generally worked, but we're seeing
problems. Some apps seem to have cached time info and not changed
(Sybase, Control-M), whilst inetd on all Solari pre 8 are reporting the
wrong time if one queries the 'daytime' service. I've seen cron have
similar problems in SunOS4 days, but this kinda surprises me. Anyone
else in Oz having problems?

Rgds,
W.

PS. Also, the patches from Sun seem to have only changed the binary, zic
compiled files. The 'australasia' source file still has problems -- it
wants to call the New South Wales timezone 'Australia/Sydney' when it
should be 'Australia/NSW'...

William,

Yes, same symptoms on all Solaris 2.6 boxes I've checked, though I have
had others say it worked OK (though I suspect they're talking about
workstations, which _probably_ have been rebooted).

We're only affected by cron, as our apps either don't care about the
local time or are easily restarted. I have only seen a problem with
processes that have not been restarted (eg. cron).

Apparently the SUN patch advised to reboot, but the comment from the
sys admins I discussed it with was "yeah, but they always say that" :-)

That's the new standard name for the time zone in Sydney.  Not all
places in New South Wales have the same time zone, so the old name was
inaccurate.  If you want the old name, compile the 'backward' source
file too.  The names changed in 1993, but Solaris 8 continues to use
the old names by default.  Maybe Sun will upgrade some day.

If you want the latest source files, then bypass Sun and get them
directly from <ftp://elsie.nci.nih.gov/pub/>.  More details can be
found in <http://www.twinsun.com/tz/tz-link.htm>.

Even if you're running Solaris 8 with all the patches, you'll need to
go to elsie to get the correct "date" output for this year's time
stamps if you live in any of the following places:

  Brazil (many locations), Bulgaria, Cuba, East Timor, Egypt, Estonia,
  Hong Kong, Iraq, Israel, Jordan, Latvia, Lithuania, Moldova,
  Mongolia, Nunavut, Paraguay, Poland, Romania, far east Siberia, and Sudan.

I guess none of these places have customers who've raised enough stink
with Sun yet.  (Wait until October.  :-)

Yes.  By far the easiest fix is to reboot.
If you can't reboot, you are in for some work.

Timezone names seem to be a big problem.

If I call date on a S 8 machine, I get:

Mittwoch, 30. August 2000, 14:12:30 Uhr MEST

Wich is wrong. It should be:

Mittwoch, 30. August 2000, 14:12:30 Uhr MESZ

MEZ ans MESZ are the official (by german time law) names for the timezone.

1. Daylight Savings time, system time, hardware time....

I am sure that this has been rehashed a bunch of times, but I can't seem
to get it through my thick  skull...

I have a RedHat 6.0 system, 2.2.13 kernel.  I need to configure the darn
thing to keep the right time.  I can't seem to correctly configure the
hardware clock so that it correctly deals with DST.

I tried setting it to UTC using RedHat's tools, but it had no effect.
The time zone information must be correct, since the calendar displays
EDT, but the hardware clock and the system clock are now exactly
backwards.....  The hardware clock is one hour ahead of the system
clock.


Wed Apr 19 13:48:25 EDT 2000
Wed Apr 19 14:48:26 2000  -0.940635 seconds

What files do I need to change (by hand, not through possibly broken GUI
tools) to make this right?

Thanks,
