Timezones… They can be difficult to work with on a global platform like the web. Some systems we help you interact want a timezone in the form of an abbreviation (EST – US Eastern Standard Time), some want it in an UTC offset (UTC-0500), and some want them in a computerized zone (America/New_York) where they auto figure out the time zone by location.

Add in Daylight savings time, and not every location uses it, and those that do have can have different starting and ending dates, well your service in one country collecting information for an event in another country, can drive you mad.

For many places where we ask for a TimeZone, we accept the computerized zones (listed below), where you pick the one that is closest to your location, then the servers figure out all the adjustments for you. For in the US, to make things we adapt over the abbreviations Eastern/EST/EDT, Central/CST/CDT, Mountain/MST/MDT, and Pacific/PST/PDT over to those zones for you.
