Time Zones for PCs?

I got a slightly odd email t’other day, from timezoneforpcs.com. Not knowing whether it was spam or not I searched on Google and found a rather interesting attempt at spamming Google itself!

I still haven’t figured out whether the program itself is a virus or whether it’s a geniune product (actually the latter looks true; the main site has quite a lot of detail). If anybody has happened to come across this before do tell!
