The system needs to stay with EST for load results and traffic reports to stay consistent. Monitoring programs need the time sync'd on all our servers and in fact are sync'ing these servers, thus undoing efforts to change the time zone.

As far as your sites and scripts you should set the TZ in each.... Or have a source login that sets this up....

Commands to include to do this:

TZ=timezone; export TZ

where timezone is the time zone wanted and that is found in /usr/share/zoneinfo.

The entire path to the timezone can be included, or just the appropriate letters. The two examples below will have the same results:

TZ=/usr/share/zoneinfo/posix/US/Pacific; export TZ

TZ=PST; export TZ
