Change time and time zone on the fly

[Joe Profaizer]

I know I can change the time on the fly, but how can I (or can I) change the time zone? I'd like to change the time zone (from CST to EST) without a reboot.

Using HP-UX 11.11

Please advise.

set_parms will do it .
But for time zone it will require a reboot .

For more information do man set_parms .

You should also investigate the affect on your application or databases before changin time or time zone .

Hi

You can change the timezone value by

set_parms timezone.(see man page of set_parms).

System may require reboot after change .Please check it .

Also see the file /etc/TIMEZONE whis is read by /etc/profile .

Hi Joe,

Time is always kept in Zulu time. All you change is how it's displayed.

So you just use $TZ to display as you see fit.

The default if no $TZ is set is kept in the
/etc/TIMEZONE file.

Rgds,

If you just want to change it for a particular user you can do:

# export TZ=EST5EDT
