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:
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)  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.
