Question:
Hello! Does this clock support IPv6?
Answer:
No, the current version only supports IPv4.

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.

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