SyncTime: JJY, WWVB & MSF

SyncTime syncs the time on your radio controlled atomic watch/clock — even when the time signal radio station is out of range.

SyncTime is comprised of a JJY, WWVB & MSF emulator/simulator.

Why Use SyncTime?
- SyncTime is completely silent.
- SyncTime allows you to override the timezone with any timezone of your choice.
- SyncTime uses NTP time for the most accurate time (requires internet).
- SyncTime allows you to sync the time when the screen is off or when SyncTime is running in the background. This feature is device dependent as some devices may close or mute SyncTime.
- No Ads.

Supported Time Signals:
JJY60
WWVB
MSF

Due to the limitations of physics and the speakers used in Android devices, these time signals are the only signals capable of being supported whilst also being fully silent.

Instructions:
1. Turn your volume up to the maximum.
2. Place your radio controlled atomic watch/clock beside your speakers/headphones.
3. Activate the time sync on your watch/clock.
4. Select the time signal supported by your watch/clock.
5. (WWVB only) Select the timezone that is set on your watch/clock. Timezones include Pacific Time (PT), Mountain Time (MT), Central Time (CT), Eastern Time (ET), Hawaii Time (HT), and Alaska Time (AKT).
6. Press the play arrow to start syncing. After approximately 3-10 minutes your watch/clock should be synced.

Note: Watches/clocks which have a 'home city' setting may need to be set to a city which can receive the official radio station time signals. After syncing, the 'home city' can be reverted.
