If not, select the correct time zone from the dropdown menu.
Here, in the Time zone box, check whether the information is correct. You can also go to Settings > Time & Language > Date & time. To fix your time zone in Windows 10, right-click the system clock in your System Tray at the bottom-right corner of the screen and select Adjust date/time. If the minutes are correct but the hour is wrong, a misconfigured time zone is probably the issue you're dealing with. Even if you fix the time manually, Windows will reset itself to the wrong time zone once you reboot. When your computer clock is off by exactly one or more hours, Windows may simply be set to the wrong time zone. It's easy for desktop computers, but might be more difficult with a laptop, depending on your model. See our guide to CMOS motherboard batteries for more information. Then after you buy a replacement, open up your PC again and replace the CMOS battery. You just have to turn off your computer, ground yourself to protect against static electricity, open the case, and check which type of battery is in your motherboard.
Thankfully, replacing the CMOS battery is pretty easy.
Every time you restart your PC, you'll find that the clock defaults to an incorrect date and time, such as January 1 at midnight. One of the symptoms is that your Windows computer no longer maintains its time and date properly. If this battery goes bad, the chip starts losing information.
