Have you ever noticed your Windows PC showing the wrong time or the wrong time zone? It may seem like a minor issue, but an incorrect system clock can cause problems with websites, email synchronization, Windows updates, scheduled tasks, and even secure connections.
The good news is that Windows makes it easy to manually change both the time and the time zone. Whether you’re traveling, troubleshooting synchronization issues, or simply prefer manual control, this guide will walk you through every available method.
As an IT technician with over 10 years of experience helping Windows users, I’ve found that many time-related problems can be fixed in just a few minutes by adjusting a few settings.
Quick Answer
To set your time and time zone manually in Windows:
- Open Settings.
- Go to Time & Language > Date & Time.
- Turn off Set time automatically.
- Turn off Set time zone automatically (if enabled).
- Click Change under Set the date and time manually.
- Enter the correct date and time.
- Choose your preferred Time Zone from the drop-down menu.
Why the Correct Date and Time Matter
Many users don’t realize how important an accurate system clock is.
Windows relies on the correct date and time for many essential services.
An incorrect clock can cause:
- Websites showing SSL certificate errors
- Windows Update failures
- Microsoft Store connection problems
- Email synchronization issues
- Incorrect file timestamps
- Scheduled tasks running at the wrong time
- Authentication problems with Microsoft accounts
For businesses, an incorrect system time can also affect network logins and domain authentication.
Automatic vs. Manual Time Settings
Windows can either:
| Automatic Time | Manual Time |
|---|---|
| Synchronizes with Microsoft or Internet time servers | You choose the exact date and time |
| Recommended for most users | Useful for troubleshooting or offline computers |
| Automatically adjusts for daylight saving time | Requires manual updates if DST changes |
| Ideal for everyday use | Best when automatic synchronization fails |

Disable Automatic Time Synchronization
If Windows keeps changing your settings, automatic synchronization may be enabled.
Navigate to:
Settings
↓
Time & Language
↓
Date & Time
Disable:
- Set time automatically
- Set time zone automatically
Windows will now use your manually selected settings.
Change the Date and Time from the Control Panel
Although Microsoft encourages using the Settings app, the Control Panel method still works.
Steps
- Open Control Panel.
- Select Clock and Region.
- Click Date and Time.
- Select Change date and time.
- Enter the correct values.
- Click OK.
Change the Time Using Command Prompt
Advanced users can also use Command Prompt.
Open Command Prompt as Administrator.
To display the current time:
time
To change the date:
date
Follow the prompts to enter the new values.
Change the Time Using PowerShell
PowerShell offers another method.
Display the current date and time:
Get-Date
Set a new date and time:
Set-Date -Date "July 5, 2026 10:30 AM"
Replace the values with your desired date and time.
This method is particularly useful for IT administrators managing multiple computers.
Why Windows Keeps Resetting the Time
If your clock changes after every restart, the problem usually goes beyond the Windows settings.
Common causes include:
| Cause | Solution |
|---|---|
| Dead CMOS battery | Replace the motherboard battery |
| Internet time synchronization | Disable automatic synchronization |
| Incorrect BIOS time | Update the BIOS clock |
| Domain Group Policy | Contact your system administrator |
| Virtual machine synchronization | Adjust VM settings |
| Dual-boot Windows/Linux | Configure UTC settings correctly |
Troubleshooting Common Time Issues
The “Change” button is grayed out
You may not have administrator permissions.
Log in with an administrator account or contact your IT department.
The time changes after every restart
This often indicates a failing CMOS battery.
If your PC is several years old, replacing the battery usually resolves the issue.
Windows cannot synchronize the clock
Try these steps:
- Check your Internet connection.
- Restart the Windows Time service.
- Verify the selected time server.
- Run Windows Update.
- Restart your computer.
The wrong time zone keeps returning
Disable automatic time zone detection before selecting your preferred time zone manually.
Best Practices
To avoid future problems:
- Leave automatic synchronization enabled unless troubleshooting.
- Regularly install Windows updates.
- Keep your BIOS firmware updated.
- Verify your time zone after traveling.
- Replace the CMOS battery if the clock frequently resets.
- Restart your computer after changing critical time settings.
Real-World Examples
Example 1: Traveling Abroad
A business traveler flew from New York to London. Windows continued using the Eastern Time Zone, causing Outlook meeting reminders to appear five hours late.
After manually selecting the Greenwich Mean Time zone, appointments displayed correctly.
Example 2: Office Computer
One client’s desktop reset its clock every morning. At first, they suspected Windows. However, the real culprit was a depleted CMOS battery on the motherboard. Replacing the battery permanently solved the issue.
