“evilandy” – That’s quite a project, a lot more than I think I’d ever need!
I’m not sure I get your point about auto DST though – it sounds like you are saying there is some relationship between having the GPS signal and adjusting the time for DST. The two are independent. The clock keeps time reasonably well without the GPS, but you have to set it and once in a while adjust it. Adding the GPS module means the clock sets itself – all you have to do is set your time zone. Are you trying to compute DST time changes based on the GPS coordinates?
I thought about getting the time from the ‘net using a wifi adapter, but the Ultimate GPS works so well, and it doesn’t have to be configured with SSID, password, etc.
