X230 Tablet (Type 3435) System Time seem to be "Frozen" after Suspend under Windows 10

[late-in-autumn]

This is an issue that I have so far only reproduced under Windows 10, but not under Linux. I have also tried searching on Google this issue and look into both the old Coreboot wiki and the new docs.coreboot.org site for information but came up with nothing.

Symptoms and steps to reproduce:

• Boot into Windows 10
• Go to System Time Setting and trigger an NTP sync to make sure the system clock is accurate
• Suspend the system either by closing the lid or through the power menu
• Wait for a few minutes in the standby state
• Resume the machine from standby
• Now notice that the system time was stuck at the time of sleep, and will keep it that way until you re-set the time either manually or through an NTP sync

Expected:

• When the system resumes from standby, the system clock should not be frozen at the time of sleep but should be the correct current time.

Additional information

• Under my Manjaro Xfce installation, when first resumed from standby, the system time displayed by the Xfce Panel clock applet also seemed to be "frozen," but it would immediately update itself to the correct time within a few seconds. However, under Windows, the system time never gets updated to the correct current time unless I manually change the clock or trigger an NTP sync.
• To maintain maximum compatibility between my Windows and Linux systems when I move between different timezones (China and the US) throughout the year, I have configured my Windows to use the UTC system clock according to the instructions in https://wiki.archlinux.org/index.php/System_time#UTC_in_Windows instead of the default local time system clock.

Thank you.

Tried disabling Hyper-V, and it did not resolve the problem.
