Time Zone Abbreviations

We deal with folks all around the world and one thing that we find that really gets in the way is getting our heads around time zones.  We can pretty much instantly convert  local tine into the time in some of the major cities in the US (such as New York, Los Angeles and Chicago) as well as many other countries. 

Time zone abbreviations are a different matter though - we always find ourselves having to look them up.  So, instead of trawling the web for them, we've put them in one place.

We're going to find these useful - we hope you do too!  We have them sorted by both abbreviation and time zone.
