Hi list
I always configure my systems to use our local time (in my case
/usr/share/zoneinfo/Europe/Zurich) and disable UTC.
What are the differences between UTC and local time? What are their
respective advantages and disadvantages?
When to use UTC?
cheers

Not sure if Zurich has any sort of Daylight Savings like we do here in
the US but that is one good reason to use UTC. Since our clocks shift
by an hour twice a year it can make log files confusing and have other
side effects. Using UTC you get a standard time that never shifts.
(Except for the odd leap second every so often.) Personally I use UTC
on my home system and let my shell convert it to my local time zone.
For servers that I manage I always use UTC to avoid the one hour shifts
of DST.
