errm, each user can change his/her timezone at will simply by doing a
"export TZ=".

There was a thread recently where a machine had users logged in from different parts of the world, each using their own $TZ, which they were setting in their .profile.

You could also set the Timezone for the users in the /etc/profile.

You don't *have* to reboot, simply changing the TZ environment variable (by editing /etc/TIMEZONE) will work for all new sessions.

However, any applications running that are timezone sensitive will need to be restarted to pick up the new TZ setting. This is not normally a huge issue as most apps use UTC instead of the local time when performing time calculations. There may be some side effects - for example your log files may have the wrong timestamps in them because the application is still running with the old TZ setting.

Generally its cleaner to reboot.

The short answer is yes.
All you have to do is change the TZ shell variable. But that will only change the timezone for that shell ant it's child processes.
You should change it for the system with 'set_parms timezone'. But as all running processes wil still have the "old" timezone it's 2cleaner" to reboot.
