I was actually looking into this as well, I wanted to have a widget that showed the time at home when you're in a different timezone. I could be wrong, but using offsets seems to be a bad idea for my application since your "local" offset could change depending on if DST is in effect. If there's any way to get more comprehensive tz info accessible via the API, I'd love to help out!
