Setting Time Zone Calibration

Linux uses the time of the motherboard CMOS chip as the Coordinated Universal Time (UTC) and determines the system time based on the configured time zone. However, Windows uses the CMOS time as the system time directly without converting it based on the time zone.

The following configuration is required:

  1. Log in to the Windows VM.
  2. Click Start, enter regedit in the Search programs and files text box, and press Enter.
  3. In the displayed Registry Editor window, choose HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > TimeZoneInformation.
  4. In the right pane, right-click a blank area and choose New > DWORD (32-bit) Value to add a REG_DWORD code. Set its name to RealTimeIsUniversal and value to 1.

    If the image does not support mouse operation, right-click can be changed to press the menu key on the keyboard, and then use the keyboard to operate.
