DST patch not reporting correct time Solaris 8

I installed the DST patch just released 109809-06, and it's various dependency patches. When I reboot and run zdump, I still get the April and October dates for DST in 2007.

I would have expected to see the March and November dates as I do on my HPUX machines and Linux boxes.

I have moved aside the zoneinfo directory and re-installed the patch. The zoneinfo re-creates itself, but I still get the old dates with:

# zdump -v EST5EDT | grep 2007

Unfortuneately this machine has the Dec 2004 Solaris 8 image and has never undergone any patching updates before I got hold of it.

Any suggestions on why the machine still see the old DST dates?

Hrm, quick update, if I manual change TZ to Canada/Eastern, the zdump returns the correct dates for DST. I am wondering if EST5EDT is the correct TZ for my machine.

My patched Solaris 9 (nine) shows the updated dates:

zdump -v EST5EDT | grep 2007

EST5EDT Wed Feb 14 20:44:30 2007 UTC = Wed Feb 14 15:44:30 2007 EST isdst=0

EST5EDT Sun Mar 11 06:59:59 2007 UTC = Sun Mar 11 01:59:59 2007 EST isdst=0

EST5EDT Sun Mar 11 07:00:00 2007 UTC = Sun Mar 11 03:00:00 2007 EDT isdst=1

EST5EDT Sun Nov 4 05:59:59 2007 UTC = Sun Nov 4 01:59:59 2007 EDT isdst=1

EST5EDT Sun Nov 4 06:00:00 2007 UTC = Sun Nov 4 01:00:00 2007 EST isdst=0

I'm in central and:

echo $TZ

US/Central

Hmm, on my machine the same thing is true. EST5EDT and US/Eastern are not identical. I have no idea why.However, using Canada/Eastern or America/Montreal is preferred over EST5DST anyway.-- Darren

Have you installed patch 108993-52 (or greater) - LDAP2 client, libc, ibthread and libnsl libraries patch. Try it, I think it will resolve problem. -Vijendra
