Daylight Saving Time is controlled by the TZ variable, set in
/etc/environment.
If you search the manual library for TZ you should find the details.
Double-check
that it's correct before you go re-setting the time. It's possible to have
different TZs for different users - possibly useful if you span time zones.
I'd
expect that to be set in the user's .profile, or similar.
Note that TZ does not cause the clock to be changed. If it's set correctly,
the
clock is always running in UCT, (sort of). TZ is just used by date, cron
and no
doubt other things to control how the real time is expressed. This is not
represented in any log, because it's not really changing anything.
I have known NTP to die if it gets too far out of sync; that might have been
your
problem. (It's not really intended to cope with big jumps in time, although
I
thought an hour was OK.) I don't know why it wouldn't have written an error
log.
