Fix AIX Time Zone Discrepancies

If the time on your AIX server is behaving strangely (ex. “date” and “uptime” output do not match), you may be able to fix the issue by re-configuring the time zone:

Launch SMIT:

smit chtz_user

Verify that your system is using the standard time zone settings. For example, the standard settings for Eastern time:

Standard Time ID(only alphabets)                   [EST]               
* Standard Time Offset from CUT([+|-]HH:MM:SS)     [5]               
  Day Light Savings Time ID(only alphabets)        [EDT]

Press ENTER to apply the changes, and verify that the times are now correct. You may need to reboot your AIX server to apply the changes to all processes.
