Very cool, thanks. But this requires the iPhone/computer to have an internet connection. I'm thinking about alternatives to GPS for non-network continuous time synchronisation.

When I read this a near week ago I immediately thought maybe try to get timing from the ripple currents sent for off / on peak items but reading some limited info decided probably not accurate enough.
Then I thought about the new digital power meters which display time and date and other info in a loop ... and ok I concluded, that's probably down to the mobile link for timing ... until I recalled where I live around the time when the telco's upgraded, the meter lost it's link for a few months - since the power drops out nearly every week the meter once power was restored still had time down to minutes correct.
