A maximum of 10 NTP Server addresses can be configured, and the program
periodically sends synchronization requests to each server address in turn. After
the synchronization is successful, the system time is written to the RTC and no
longer continues to send synchronization requests to the later NTP servers.
In addition to using NTP to synchronize the time, there is a synchronization
button in the Device Info status page to synchronize the time manually, but only
when the device time and the local time (the time of accessing the computer used
by the device) differ by more than 3s, this synchronization button will be
displayed.
Configuration import, export and factory restore are supported here.
