After the TZ change:
A reboot is not mandatory. A reboot is recommended so processes started before the change are in sync. Sometimes, only database applications require a restart to pick up time changes. If you cannot reboot immediately, check with your application teams to determine which applications should be restarted.

Testing Tip: See AIX Time Zone: Sample Perl script to test TZ changes without impacting the system time
