SO. I'm going to present it in the form of a static page with a persons local timezone and UTC highlighted, but thought I'd list all other timezones on it as well.
However, there's a million and one timezone. So, request time:
Supported php timezones. Everyone can pick one that they need or want and I'll add it to the site. Just reply here.
Also, it's got to be one that's listed on the list, so...
ALSO, not one from the Others page as they're just legacy features that don't take DST into considertion.
