Beijing time Plus 8 hours, 17+8-24=1, just a little
The timer in the program, the original is 1 minutes, according to the system time corresponding adjustment, also want to increase 38 seconds, so in that time length of 1 minutes 38 seconds (actual time or 1 minutes, but to the end of the "moment" moved back 38 seconds)

The failure of this is very covert and is hereby remembered.
