Mapping US zip code to time zone

I just found a free zip database that includes time offset and participation in DST. I do like Erik J’s answer, as it would help me choose the actual time zone as opposed to just the offset (because you never can be completely sure on the rules), but I think I might start with this, and have it try to find the best time zone match based on offset/dst configuration. I think I may try to set up a simple version of Development 4.0’s answer to check against what I get from the zip info as a sanity test. It’s definitely not as simple as I’d hope, but a combination should get me at least 90% sure of a user’s time zone.
