Australia here, no radio time as far as I know. Lately I've been wondering whether accurate time could be derived from terrestrial digital TV signals.

Thanks for sharing > Because it works by exploiting this leakage, Time Station Emulator works best with a built-in speaker of a phone or tablet. > In some cases, wired headphones or earbuds may also be suitable. > Higher-frequency harmonics are considered artifacts beyond the range of human hearing, so they are routinely suppressed by audio compression algorithms and better equipment. > Bluetooth devices and audiophile-grade equipment are therefore less likely to work.
- RossBencina 2mo agoVery 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.
- anenefan 2mo agoWhen 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.
