Time Zone Master, available for free from www.relativedata.com, is a 
windows programme that uses geonames cities15000.txt then the olson tz 
database to represent times and locations in the past and future. It 
also does some interesting astronomical time calculations as well 
(sundial time, moon phases, sunrise/sunset, and seasons)
