Hi Ferdi,

you can set the timezone using "set_parms timezone". This will let you select the correct timezone.

Hope this helps,
SP,

It is perfectly legal to define TZ and put it in /etc/TIMEZONE. Man 5 environ for details about the TZ format. You only need an entry in /usr/lib/tztab if your country has something similer to Daylight Saving Time or Summer Time otherwise, no entry is needed.

The set_parms command won't help here because it only knows a few common timezone values. In fact, you don't even need to edit tztab although this would be a more conventional location. The man page for environ describes how you can create your own timezone. The file is called /etc/TIMEZONE and if you edit this file to read:

TZ=TEH-3:30
export TZ

Note that I just made up the timezone name TEH (per man environ). If you don't observe daylight saving, this is the only change you need. Each time you login, you'll have your local time. Note that depending on what your current server is set to, you may need to change the HP-UX clock (which is GMT/UTC), then reboot.
