See the LIVE DEMO of the DS3231 in Action! Compare with Other Real-Time Clocks.
Twice per minute, the DS3231 time-keeping demonstration checks and displays the time differential between a tier-one time server and the DS3231's integrated RTC/TCXO/crystal. The demo also shows the time when the DS3231 was last synchronized with the time server, the delta between them in ppm, and the temperature of the DS3231.
