How can I change in HP-UX The time zone
to reflect the Jerusalem/Israel time zone (I think ist called IDT or IST) ?

tnx

In theory, it should be easy. You just add an entry to /usr/lib/tztab and set your TZ environment variable to the new entry. If there is no switch into daylight savings time, you do not need any entry in tztab. And the is a "man tztab" to guide you.

But you need to know when the daylight savings shift occurs. That is a real problem with Israel. See this page for details. Edit: Here is a file with an entry for 1992-2038. If you go up one level from here you will see an INSTALL file which you should ignore. It is for HP-UX 9.x and it is not a very good procedure even for that OS.

i was searching for this-> "how can i change time zone in HP-UX to Nepal time zone" and i came across this->"How can I change in HP-UX to Jerusalem time zone". seems like somebody knows much about this topic. please help me too?

How can I change in HP-UX The time zone
to reflect the 'Minsk' (capital of Belarus) time zone, its EEST +0300 Eastern Europe Summer and have 1 hour daylight savings.

Thanks in Advance,

Same as western Russia?
WST-3WSTDST

The best is to user the (interactive) set_parms command...
man set_parms

Using set_parms you would have found:
Belorussia (minsk) Time, Belorussia (minsk) Daylight Savings Time
WST-2WSTDST

In HP-UX.
First prepare /usr/lib/tztab (if your timezone is not there).
See "man 5 environ" for the syntax of TZ.
Update "TZ" in file /etc/TIMEZONE .
