Question:
When there is interruption of network, is there any indication? And will the clock still display correct time?
Answer:
Normally the clock synchronizes with NTP server every 5 minutes. When there is interruption of network, a small dot will appear on the right bottom corner of the LED display and the clock won’t synchronize, so it will be inaccurate slowly, the deviation is about 1 minute per day. As soon as it is connected to network again, it will display correct time automatically and the dot will disappear.
Question:
Can we set up the time without a NTP server?
Answer:
It does require some NTP server, such as a private NTP server or internet based source( internet public NTP server). With that available, it will keep itself accurate and on the money.

When there is interruption of power supply, will the clock work?
