That way, the system takes care of things like daylight savings time automatically, but things like cron jobs run based on local time. The only drawback is that the timestamp in the logs can get confusing sometimes, because while most things are logged using local time, some things are logged using the hardware clock... The way I understand it, regardless of how you have your hardware clock set, Linux uses UTC internally, and converts to local time as necessary to display the time/date. At least it does if you have set things up correctly. It is possible to have the hardware clock set to local time, tell Linux it is set to UTC, and that UTC is the local time zone. (You have to work at it to set it up this way...)
