AIX timezones - a way around rebooting?

UNIX AIX
1

Hi,

I've got a bunch of IBM AIX 5L 5.3 and 5L 5.2 servers here that I've inherited from my predecessor in a new job, and I'm trying to sort out their timezones. A number of them need to have their timezones changed to the correct setting - it would appear that they were not configured properly in the first place.

Ordinarily, this would not be a problem - edit the /etc/environment file and reboot. Except that these AIX servers are 24/7/365 production servers, and cannot be rebooted. Therefore, I need a way to tell AIX to re-read the /etc/environment file and set the system timezone properly WITHOUT having to reboot.

Is this even possible?

Try export TZ=bst0gmt and set the time with the date command.

Great stuff - it works. Wonder why smitty tells you to reboot your system instead of just setting this environment variable itself for you? stupid thing.

Thanks loads!
