Start with "date -u".
Since this is a 'virtual' server the hardware real time clock is virtualized and
not under your control.
You should ask how the host keeps time. Linux has two notions of
the real time clock. It is correct local time OR it is GMT. In the virtual
host world there is a third case where your local time is not local time
for the hardware.
It may be that you need to use ntpdate at start time and ntp normally.
It may also help to have system time set to hardware local time
and add an environment variable (TZ) for users. This works as long
as "date -u" returns correct UTS time (GMT).
