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 Simon -- XMPP: sjolle at swissjabber.org

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.

Windows expect the clock to be set to localtime.
