Unix systems should be run in GMT/UTC (almost the
same thing; GMT is _not_ British time").
You then use $TZ in the environment, or some OS-dependent
way of setting 'localtime' (eg, a symlink /etc/localtime,
or some other method) to let programs show the time in
the local zone. That's normally handled by libc.
Machine's internal clock is (and has always been) in UTC. TZ
environment variable is set (in /etc/TIMEZONE) to US/Eastern
which supposedly does automatically handle timezone change. From
what I can tell by comparing files found in /usr/share/lib/zoneinfo,
US/Eastern is same as setting to EST5EDT (to test this I changed
setting TZ in TIMEZONE file to EST5EDT and rebooted. Same behavior
as if TZ set to US/Eastern).
It's really just asking the operating system for
"the current time", so the OS is not using GMT.
IS there any way of verifying that INTERNALDATE has access/is using TZ
environment variable i.e. are we setting/using it correctly? Some here
are thinking that it sounds like it might be a cyrus bug if changing
the server time changes the behavior.
