LOL Unfortunately it is the only way that works reliably - you (or someone) have to set it (if you have a 3G or something interface, as well as a GPS receiver, the local phone company may broadcast local time, and you could work out the timezone offset from that (or of course, you could just use their time setting...) The problem is that even if you do all the work that others have suggested, to collect all the boundary data (and you could actually convince yourself that your data actually matches the actual practices - which means that the nominal political boundaries aren't always appropriate), you still end up with just knowing the zone you're in, and not necessarily the correct offset. You can believe what's in the database, but that's only accurate if your device has a current copy, the data changes many times a year. If your device has the ability to fetch updated database copies when they're needed, then it must be connected to the net somehow, and if it is, it can probably make use of that to find some local system with local time that you can get. Time seems like it really ought to be simple to deal with, unfortunately it is absurdly complex. kre
