When the system wakes up from sleep, the system time changes to the time of the last shutdown.
When the computer wakes up from hibernation or sleep mode, the system time displays the time of the last normal shutdown, which differs from the actual time by several hours or even several days. You must manually click Sync Now or restart the time service to calibrate it. I have replaced the CMOS battery and confirmed that automatic time setting is enabled, but the problem persists.
