Is it actually receiving WWVB, et al., or jusy synchronizing with, for example, an NTP server and then using that to generate an audio signal you can "manually"

- sizzzzlerz 9y agoI don't think the iPhone nor any Android phone have the necessary circuitry to receive the WWVB signal directly. THey do, however, keep time sync with NTP or some NTP-like service over the wireless network or wifi. That should keep it's knowledge of time accurate to a second or two.
- LeoPanthera 9y agoIt simply broadcasts the time on your iPhone (the source of which is usually time.apple.com) as a WWVB-compatible radio signal.
