My last post about a world map inspired me to find a time zone map that could be used in Visio. I found an SVG map at
http://upload.wikimedia.org/wikipedia/commons/6/68/Standard_time_zones_of_the_world_%282012%29.svg that I could convert, and link a list of time zones from
http://en.wikipedia.org/wiki/List_of_time_zones_by_UTC_offset that I put into Excel.
I have used Visio’s Color By Value Data Graphics, so you can easily edit the colour scheme.
You can download this map from http://sdrv.ms/1bCUSXx
