Solution 7 – Change the time synchronization server

After selecting a different server, check if the problem is resolved.
Solution 8 – Check your battery
According to users, some of the most common causes for incorrect time on your PC is your motherboard battery. If you don’t know, your PC has a built-in battery that allows BIOS to save settings and keep the clock running while your PC is turned off.
However, your battery can get drained or damaged after a while, and if that’s the case, your PC won’t be able to keep track of time anymore, and you’ll end up with this kind of problem. However, you can check if your battery is the problem with ease.
To do that, simply enter BIOS and adjust your time and date from there. Now save changes and boot to Windows. If your date and time are still correct, turn off your PC and disconnect it from the power outlet.
Leave your PC like that for an hour or two. Better yet, leave it disconnected from the power outlet over the night. After leaving the PC unplugged for a couple of hours, turn it back on again. If the issue reappears, it’s rather likely that your battery is faulty.
To fix the problem, you’ll need to purchase a new motherboard battery and replace the faulty one. If you don’t know how to do that, or if your PC is under warranty, it might be best to contact the official repair center.
Incorrect system time can be a big problem, but we hope that you managed to fix this issue on your PC by using one of our solutions.
