*****************
When your box says $TZ is "GMT+5", here's what it means:
1) There is a line in /etc/default/init that says:
TZ=GMT+5
2) There is a *file* in /usr/share/lib/zoneinfo named "GMT+5":
% ls -l /usr/share/lib/zoneinfo/GMT+5
-rw-r--r-- 2 root bin 58 Jan 8 2000 /usr/share/lib/zoneinfo/GMT+5
This file was created by:
# cd /usr/share/lib/zoneinfo
# zic src/etcetera
# zic src/backward
The zoneinfo source files (in src/) are ascii text, format defined
by the zic(1M) man page.
Now, forgive my boldness, but I'm guessing you're in India (because
that's the only place I know with a +5.5 hour time zone). Probably
what you *really* want is to change your /etc/default/init entry
to:
TZ=Asia/Calcutta
...and reboot.
This zone has an offset of +5.5 hours from UTC, and reports as IST.
NOTE: Depending on who installed your machines, you may not have a
/usr/share/lib/zoneinfo/Asia/Calcutta file. Not to worry. Check
first, and if the file is not there:
# cd /usr/share/lib/zoneinfo
# zic src/asia
This is completely safe. Once the zone files are there, you can play
with them. I'm on the west coast of the US.
% echo $TZ
US/Pacific
% date
Wed Jul 4 09:58:30 PDT 2001
% TZ=Asia/Calcutta
% export TZ
% date
Wed Jul 4 22:28:36 IST 2001
% TZ=Australia/Tasmania
% date
Thu Jul 5 03:00:08 EST 2001
Once you're satisfied, make your change to /etc/default/init and reboot
*******************
On Solaris 7 there should be a file called init in /etc/default that allows
you to set your timezone.
Hope that helps.

HI,
first check if there isn't a timezone definition for your
country in /usr/share/lib/zoneinfo
If there is (you might need to do a "zic continent" to create the
continent's country's timezones), then add the equivalent to the following in
/etc/TIMEZONE: "TZ=Continent/Capital" or "TZ=Continent/Country"
A reboot might then be needed, but I've heard that you could
just send a SIGHUP to init to "fix" it.
