There are many sources of world time zone data and maps available. I have combined several of them into a single file for Google Earth which will let you easily switch between the different versions and use the one that works best for your purpose.
Eric Muller Version – This version covers the United States only. It is included because it has a much greater level of detail than other time zone maps of the Unites States.
Valery35 Version - Created by Valery35 at the Google Earth BBS. Static map consisting of colored polygons showing the time zone boundaries.
Shimakaze Version - Created by Shimakaze at the Google Earth BBS. Static map consisting of the time zone borders. I’m including it because the resolution of the data appears to be greater than any of the other sources.
Barnabu Version - Created by Barnabu of the the Google Earth Visualization Blog. Dynamic map which shows polygons of the time zones. Clicking on one of the time zone polygons shows the current Standard time and GMT offset.
CIA Word Factbook Version - From the CIA World Factbook. This is a traditional digital map that I converted to be viewed in Google Earth.
H.M. Nautical Almanac Office Version – From the U.S. Naval Oceanography Portal. Another digital map the I converted to be viewed in Google Earth.
If you know of any other good time zone data or maps, please post a comment and I will try to add it to this collection.
Note: Given the complexity of how global time zones work, there are likely errors and inconsistencies with most/all of these maps and none of this data should be considered “official”. Here is a great source of time zone data.

Please see worldtimeengine.com for more accurate data. We also provide premium high-quality GIS-based timezone maps (or KML-based timezone maps) though we don’t advertise this on our website. There’s something of an exclusive and let me know if you want to chat.
Rich, I had to laugh at your comment about “more accurate data”, when I tried your website today it tells me that Cape Town is in Guinea-Bissau….sure ! See> Capé, Bafatá, Guinea-Bissau (Cape , South Africa)

nice information this helps me to get update information from all over the world
Just checked out Barnabu world time clock…BOY IS IT WRONG!!!…Said the date and time in Kiribati (Kiribass) is Friday, Dec 31, 2010 12:34 and GMT -1o hrs…Kiribati has three time zones and has already seen the New Year…This is really bad.
Kiribati should be 12, 13, and 14 hours AHEAD of GMT, not behind.
Not sure if OnTimeZone.com would be of interest to you. It contains updates of changes in the US as recent as Nov 2010.
