How to Fix System Time, Date, and Time Zone in Windows (2026 Guide)

Is your Windows PC showing the wrong time or date? You’re not alone. A wrong system clock can cause issues with SSL certificates, Windows Update errors, app crashes, and even login failures. The good news is that fixing your system time, date, and time zone in Windows is quick and easy — even for beginners.

In this guide, we’ll walk you through every method to fix the system time, date, and time zone in both Windows 10 and Windows 11.

Why Does Windows Show the Wrong Time or Date?

Before fixing it, it helps to understand why Windows displays incorrect time. Common causes include:

• Dead or failing CMOS battery on your motherboard
• Windows Time service stopped or disabled
• Wrong time zone selected in settings
• Internet time sync turned off or misconfigured
• Third-party software or dual-boot setups changing the hardware clock

Now let’s fix it step by step.

Method 1: Fix Time and Date from Windows Settings (Quickest Way)

This is the fastest and simplest method that works on both Windows 10 and Windows 11.

1. Right-click the clock in the bottom-right taskbar.
2. Click “Adjust date and time”.
3. In the Date & Time settings window, toggle “Set time automatically” to ON.
4. Also toggle “Set time zone automatically” to ON.
5. Scroll down and click “Sync now” under the “Synchronise your clock” section.

Windows will immediately sync with Microsoft’s internet time servers and correct your clock. This resolves the issue in most cases.

Method 2: Manually Set the Correct Time Zone

If automatic time zone detection isn’t working correctly, you can set it manually.

1. Go to Settings → Time & Language → Date & Time.
2. Turn OFF “Set time zone automatically”.
3. Under the “Time zone” dropdown, select your correct region — for example, (UTC+05:30) Chennai, Kolkata, Mumbai, New Delhi for India.
4. Your clock will immediately update to the correct local time.

Selecting the wrong time zone is one of the most overlooked causes of wrong time display in Windows. Always double-check this setting, especially after reinstalling Windows or setting up a new PC.

Method 3: Manually Set Date and Time

If your PC is offline or automatic sync keeps failing, you can set the time manually.

1. Go to Settings → Time & Language → Date & Time.
2. Turn OFF “Set time automatically”.
3. Click the “Change” button under “Set the date and time manually”.
4. Enter the correct date and time, then click Change.

This is useful if your PC doesn’t have an internet connection or the time server is unreachable.

Method 4: Restart the Windows Time Service

If the time keeps going wrong after a restart, the Windows Time (W32tm) service might be disabled or crashed. Here’s how to restart it:

1. Press Win + R, type services.msc, and press Enter.
2. Scroll down and find Windows Time.
3. Right-click it and select Restart. If it’s stopped, click Start.
4. Double-click the service, set Startup type to Automatic, then click OK.

This ensures the time service runs automatically every time Windows starts, keeping your clock in sync.

Method 5: Re-register and Force Sync via Command Prompt

For advanced users or persistent sync failures, use Command Prompt to force a time sync:

1. Press Win + S and type cmd.
2. Right-click Command Prompt and choose Run as administrator.
3. Type the following commands one by one, pressing Enter after each:

net stop w32tm
w32tm /unregister
w32tm /register
net start w32tm
w32tm /resync /force

This completely re-registers the Windows Time service and forces an immediate sync with the time server. It’s one of the most effective fixes for stubborn clock problems.

Method 6: Change the Internet Time Server

If Microsoft’s default time server time.windows.com isn’t working well in your region, you can switch to a different NTP server like time.google.com or pool.ntp.org.

1. Go to Settings → Time & Language → Date & Time.
2. Scroll down and click “Additional clocks” or open Control Panel → Date and Time → Internet Time → Change settings.
3. Replace the server address with time.google.com or pool.ntp.org.
4. Click Update now, then OK.

Method 7: Replace the CMOS Battery

If Windows resets your clock every time you shut down or restart — even after syncing — the CMOS battery on your motherboard is likely dead. This small coin-sized battery (CR2032) holds your hardware clock settings when the PC is powered off.

To fix this, open your PC case (or laptop, with care), locate the flat round battery on the motherboard, and replace it with a new CR2032 battery available at any electronics or hardware store. After replacement, set the date and time again in BIOS/UEFI and in Windows settings.

This is a permanent fix if a dead CMOS battery was the root cause. CMOS batteries typically last 5–10 years.

Bonus: Fix Time Issues in Dual-Boot (Windows + Linux)

If you dual-boot Windows and Linux and your time keeps going wrong in Windows, it’s because Linux uses UTC hardware clock while Windows uses local time. The easiest fix is to run this command in Linux:

timedatectl set-local-rtc 1 --adjust-system-clock

This forces Linux to use local time, preventing it from conflicting with Windows.

Final Thoughts

A wrong system time in Windows might seem minor, but it can cause serious problems — from failed Windows Updates to broken app authentication. Fortunately, fixing your system time, date, and time zone in Windows is straightforward once you know which method to use.

Start with Method 1 (automatic sync from Settings) — it solves the problem in 90% of cases. If the issue keeps recurring, check your CMOS battery or use the Command Prompt re-sync method.
