I've never been very good about timezones on this site. For a long time, all the times were in Pacific (US) time. Then for a couple months now they've been in Central (US) time. In both cases, sometimes the time would change for things like Daylight Savings Time. That's not good.
As of about 5 minutes ago, however, all new times going forward will be in GMT (also known as UTC). That should be much clearer. Also means that the time won't be jumping around by an hour for Daylight Savings Time. Please report any problems here.
