It seems that the old timezone settings on TSC were messed up and broken, so I added a new timezone system. This timezone system works on POSIX tzdata, so daylight saving time is handled automatically.
To set your timezone, goto User Settings, Display. Select your timezone from the dropdown box.
In case you're wondering why there's so many timezones in the list, I'm using PHP's timezone_identifiers_list() function, which returns *all* supported timezones. Better to have more timezones than not enough. :)
Also note that this does not affect times displayed on the forums (yet), so you'll still need to adjust the SMF time offset via the SMF profile editor.
EDIT, 2007/12/30 06:26 PM: It seems that some parts of the timezone listing were confusing. If you're in the US and you can't figure out which city to select, scroll to the bottom and select a "US/" timezone. This will work for most of the US, but if you live in some place like Phoenix that has weird DST rules, you should select the specific city.
