Windows 10: Change System time in PC BIOS setting, but still restore to original time when boot into...

I'v tried to change time in PC BIOS setting to earlier(e.g. change from 17:00 to same day 08:00), after saving change and boot to Windows 10 desktop the system time will be restore to original 17:00.


However, if just change few hours, maybe 1 or 2 hours, boot to Windows 10 desktop will be the time I changed.


Wondering if Windows 10 has a checking mechanism to prevent this kind of change?

Can't able to change the system time

Hi,

If the system time is not changing after configuring the date and time settings on Control Panel, most likely, the BIOS clock is also incorrect. We suggest making sure that the date and time settings on your computer is properly configured. To configure
the date and time settings, follow the steps below:

• In Cortana search, type control panel.
• Choose Control Panel from the list.
• Select Clock, Language, and Region.
• Click Date and Time.
• Click Change date and time, then set the correct information.
• Click Change time zone, then select the correct time zone.
• Click Apply and then click OK.

If the system time still didn't change, we recommend that you contact the computer manufacturer for further assistance on how to check and configure the BIOS clock of your device.

Feel free to post back if you have other concerns.

 

Changing Time Format

Hi Mary,

There's a possibility that the set up time format in your computer Basic Input/Output System (BIOS) is military time. To have this checked, you can try to reset the time of your computer through Control Panel. See the steps below on how to do
so:

• Open Control Panel > Clock, Language, and Region >
  Change date, time, or number formats. This would open the
  Region window.
• From there, click on Additional settings at the bottom part. It will open the Customize Format.
• Click Reset; then, OK.

The steps should work; however, if not, we suggest that you contact manufacturer and have the BIOS time checked.

Let us know what happens after doing the suggestions .

 

Time keeps randomly changing (time zone settings are correct, not BIOS related)

Hi Erik,

If your system time keeps changing, you may need to synchronize your PC's clock with an Internet Time Server. This can help ensure that your PC's time is accurate. Please note that you need to connect to the internet at least once a week to for the synchronization
to occur.

If your PC is on a domain, you can't synchronize your clock with an Internet time server. Your clock will automatically synchronize with the domain controller instead.

You can follow these steps to integrate you PC's clock with an Internet Time Server:

• Open the Control Panel in small icons view.
• Click on the Date and Time icon.
• Click on the Internet Time tab.
• Click on the Change settings button.
• Click Yes if prompted by User Account Control.
• Check the Synchronize with an Internet time server box and select a time server from the drop down.
• Click on Update now.
• When the clock is successfully synchronized, click on OK.
• Click on OK.

Note: If you PC's time or date is set incorrectly by too much, it can cause an error when trying to synchronize your clock. If an error occurred (Step 8), then click on
Update now again.

If you need further assistance, let us know.
