TrueOffset

RADIO TIME CODES, SPELLED OUT A clock sold as "atomic" is really a radio, listening to a distant station that spells out the time one second at a time. TrueOffset now plays those codes, timed to the true second, and shows each one being read as it arrives: WWVB, DCF77, MSF, JJY (40 and 60 kHz), and BPC, plus the codes of WWV, WWVH, CHU, and Australia's VNG. That makes fourteen signals in all, each built from its station's published sound and timing. None of them is a recording. - Set a Radio-Controlled Watch (beta): lay a watch on the speaker and let it listen. It has set a Citizen Eco-Drive in Australia, far out of WWVB's reach. If you try it, tell us how it went. - DCF77 weather: switch it on, and your local forecast rides in the code's weather seconds, the way Germany's station once sent its own. TrueOffset asks for your approximate location only when you turn this on. - The Lincolnshire Poacher: a shortwave mystery, not a time signal. It plays only when you ask for it. ALSO NEW - Help in the app: what an offset is, why clocks drift, what each screen shows, and what TrueOffset asks for and why - On Wi-Fi, a note says how much of the offset can be network delay - A new default reference, ntp.trueoffset.app, a Safran SecureSync 1200 with its own rubidium atomic clock - The Quality ranking names the steadiest of three or more servers - Clearer, higher-contrast text throughout - Public servers now get one request per poll, as their operators ask - TrueOffset is now on the Mac, too, free in the same App Store listing
