Windows 10 system time jumping back can be a frustrating issue. It may cause problems with scheduled tasks, software updates, and even security certificates. Fortunately, there are several straightforward steps you can take to fix this problem.
In this guide, we will walk you through basic troubleshooting methods to correct the system time on your Windows 10 computer. Each step is explained clearly to help even beginners follow along easily.
Correct system time is important because many applications rely on it to function properly. If your clock is inaccurate, you might face errors or unexpected behaviors.
Let’s get started with some quick checks and then move on to solutions that often resolve time jumping issues.
Quick Note: Prerequisites and Basic Checks
- Make sure your PC is connected to the internet. Windows needs internet access to synchronize time with online servers.
- Check your time zone settings. Incorrect time zones can make your clock appear wrong.
- Verify that your computer’s CMOS battery is functioning if the time resets after shutting down. A dead battery can cause time issues.
- Ensure you have administrative rights to make system changes.
Step 1: Check and Set the Time Zone Correctly
An incorrect time zone can make your clock seem like it’s jumping back or forward. To fix this:
- Click on the Start menu and select Settings.
- Go to Time & Language and then select Date & time.
- Under Time zone, choose your correct time zone from the dropdown menu.
- Turn off Set time zone automatically if it’s causing issues, and set it manually.
Setting the correct time zone ensures that Windows calculates your local time properly.
Step 2: Enable Automatic Time Synchronization
Windows can automatically synchronize your clock with internet time servers. This helps keep your system time accurate.
- Still in the Date & time settings, make sure Set time automatically is turned on.
- Scroll down and click on Additional date, time & regional settings.
- In the new window, click on Date and Time.
- Go to the Internet Time tab and click Change settings….
- Check the box for Synchronize with an Internet time server.
- Choose a server like
time.windows.comortime.nist.govfrom the dropdown. - Click Update now and then OK.
This synchronization ensures your PC’s clock matches official time servers regularly.
Step 3: Restart Windows Time Service
Sometimes, the Windows Time service may malfunction, causing time jumps. Restarting it can help.
- Press Windows + R keys to open the Run dialog box.
- Type
services.mscand press Enter to open the Services window. - Scroll down and find Windows Time.
- Right-click on it and select Restart. If the service is stopped, select Start.
- Double-click the service, set the Startup type to Automatic, and click OK.
Restarting the service refreshes time synchronization processes and can fix glitches.
Step 4: Check and Replace CMOS Battery (If Applicable)
The CMOS battery on your motherboard keeps the system clock running even when your PC is off. If this battery is dead, your time may reset or jump back.
You might notice the time resets after a complete shutdown or unplugging.
How to check and replace:
- Turn off your computer and unplug it.
- Open your PC case carefully (for desktops) or remove the back panel (for laptops), following manufacturer instructions.
- Locate the small, round battery on the motherboard (usually a CR2032 coin cell).
- Remove it gently and replace it with a new battery of the same type.
- Close the case, plug in your PC, and turn it on.
If you’re uncomfortable opening your PC, consider seeking professional help or contacting the manufacturer.
Alternative Method: Use Command Prompt to Resync Time
If the graphical interface doesn’t resolve the issue, you can force a time sync using Command Prompt.
- Press Windows + X and select Windows Terminal (Admin) or Command Prompt (Admin).
- Type the following commands one by one and press Enter after each:
net stop w32time
w32tm /unregister
w32tm /register
net start w32time
w32tm /resyncThese commands reset the Windows Time service and force synchronization.
FAQs
Why does my Windows 10 clock keep jumping back?
This is often caused by incorrect time zone settings, a malfunctioning Windows Time service, or a dead CMOS battery.
Can malware cause time issues?
Yes, some malware can alter system time. Running a full antivirus scan is recommended if you suspect infection.
Is it safe to disable automatic time setting?
Disabling automatic time setting is not generally recommended as it can lead to incorrect time. However, it can be temporarily useful for troubleshooting.
How often does Windows sync time automatically?
Windows typically syncs time once a week, but this can vary based on system activity and settings.
What happens if my CMOS battery dies?
Your system might lose time and BIOS settings when powered off, causing the clock to reset or jump back.
When Nothing Works
If you’ve tried all the above steps and your system time still jumps back, consider the following:
- Run a full system antivirus scan to rule out malware interference.
- Check for Windows updates and install any pending patches, as some updates fix time-related bugs.
- Restore your system to a previous restore point where the time was working correctly.
- Consult the official Microsoft Support page for Windows Time issues: Microsoft Date and Time Fix.
- If hardware is suspected, contact your computer manufacturer or a professional technician.
Conclusion
Fixing the Windows 10 system time jumping back issue usually involves simple checks and adjustments. Start by confirming your time zone and enabling automatic time synchronization. Restarting the Windows Time service or using Command Prompt commands can often resolve more stubborn problems.
If hardware is the root cause, replacing the CMOS battery may be necessary. Always ensure your system is secure from malware and fully updated.
By following these step-by-step instructions, you should be able to keep your Windows 10 clock accurate and avoid disruptions caused by incorrect system time.
