Windows操作系统时间跳跃 System time synchronized with the hardware clock

操作系统:windows 8.1, 某一天系统自己跳跃了一个小时,机器没有联网, 并且时间设置上禁用了夏令时,查找Windows 系统日志,有如下的描述:

"The system time has changed to ‎2021‎-‎10‎-‎24T09:45:22.500000000Z from ‎2021‎-‎10‎-‎24T10:45:31.235292400Z.
Change Reason: System time synchronized with the hardware clock."

系统没有重启过,怎么会自己跳1小时呢?hardware clock 和夏令时有关么?
