Summary of the phenomenon of clock jumping from 11:59 to 4:00:
1. As long as there is no operation to set the time, the device runs normally, or it shuts down and starts up again, and the clock has not had any problems.

2. The clock was reset to around 10 o'clock, and when it ran to 11:59, the clock became 4:00 o'clock.
