[time-nuts] Smart Phone time display accuracy...?

[Severin Haas]

The German PTB has a nice widget (https://uhr.ptb.de) to see the actual
time + deviation ("Abweichung"). Can not test this from another location
than UTC+1h, but probably it works at your location.
Does anybody of you know how they are measuring the time deviation? Some
JavaScript Voodoo?
