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.
