Time for the twice-annual public service announcement: Daylight Savings time is stupid. If you run Internet servers and/or collect logs be sure you do everything in UTC. Saves a lot of heartache.
Some bad software forces you to choose your time zone off a map, making it impossible to select UTC. A handy trick is to choose Reykjavik, Iceland time. Since 1968 Reykjavik hasn't changed clocks for daylight savings and is identical to UTC. That could theoretically change in the future.
