Welcome the world of pain that is timezones and DST... As someone who has had to write an extensive amount of deal with these two concepts they are the worst things ever. We should just abolish timezones, DST, and move to the International Fixed Calendar. Time sucks. I'm even in favor of moving to a seconds-based time unit like kiloseconds, miliseconds, etc instead of minutes/hours/days/weeks/months/years/etc. "Metric Time" if you will...
