I added a simple patch to change the way timezones are sorted by default, in a way that I think is more user friendly. With this change, we sort by (GMT offset, name) rather than just by (name). Since the names tend to be hard to guess - my personal timezone is "America/Vancouver" even though I'm in Canada? - this makes it easier to find things in the list.
Sort timezones in order of GMT offset, not just name.
