How to Fix Windows and Linux Showing Different Times When Dual Booting

Here we can see, “How to Fix Windows and Linux Showing Different Times When Dual Booting”

If your system dual boots both Windows and Linux, you might notice that it’s impossible to urge the system clocks to sync. Regardless of how you modify the punch in one OS, it doesn’t fix the matter with the opposite OS. This is often due to a disagreement about timekeeping methodology between Windows and Unix-based operating systems. Fortunately, there’s a comparatively easy fix for that.

Why does this happen?

Your computer stores the present time during a clock in your motherboard. This enables the pc to stay track of your time even when turned off. To account for time zones, different operating systems use other methods. Windows assumes the civil time is stored within the motherboard, so it doesn’t apply any quite zone offset. On the other hand, Linux will interpret the time on the motherboard as UTC (a.k.a. Greenwich Mean Time) and use a timezone offset to display civil time.

Both of those systems work perfectly fine independently. The matter occurs once you dual boot a system, running Windows and Linux off an equivalent motherboard. When the operating systems are forced to share a time store, the clocks won’t sync.

There are two alternative ways to fix this problem: we will change how Linux interprets the stored time or do an equivalent to Windows.

Option 1: Make Linux use local time

The most reliable thanks to making Linux and Windows agree on the time is to vary Linux’s timekeeping methodology. While this isn’t explicitly supported, it’s slightly more reliable than doing an equivalent in Windows. It works on any flavour of Linux using the system, which incorporates Ubuntu, Fedora, Red Hat, Debian, and Mint. Changing the Windows time typically works fine, but it can sometimes cause instabilities in third-party software that expects the stored time to be civil time.

1. Open Terminal and run the subsequent command:

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

This will tell the system to interpret your motherboard’s stored time as civil time. Linux will not apply zone adjustments to the time stored on the motherboard. As a result, your clocks will sync.

If you ever got to reverse the command, change the 1 to a 0:

timedatectl set-local-rtc 0 --adjust-system-clock

Option 2: Make Windows use UTC

You can also change the way that Windows views system time. This tweak will cause Windows to interpret the time stored on the motherboard as UTC, which Linux can then interpret because of the correct zone. While this generally works well, some applications believe motherboard nonce civil time. As a result, hard-to-track bugs can sometimes appear. That creates this feature slightly less desirable than the primary.

1. Disable “Set time automatically” under “Time & Language” within the Settings application. This may prevent Windows from reverting the changes we’re close to making.
2. Open Registry Editor by typing regedit within the Start Menu.
3. Find the subsequent registry key within the left pane of the registry editor. To urge there quickly, paste the situation into the registry editor’s address bar:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TimeZoneInformation

4. Right-click on the “TimeZoneInformation” key within the left pane and chose “New -> DWORD (32-bit) Value” from the context menu.
5. Name your new value “RealTimeIsUniversal.”
6. Double-click on the worth you only created, set its value to “1,” and click on “OK.”

User Questions:

1. Why is that the time wrong on Windows?

When your computer clock is off by exactly one or more hours, Windows may be set to the incorrect zone . … you’ll also attend Settings > Time & Language > Date & time. Here, within the zone box, check whether the knowledge is correct. If not, select the proper zone from the dropdown menu.

2. Why does Windows time keep changing?

The punch in your Windows computer is often configured to sync with an online time server, which may be helpful because it ensures your clock stays accurate. In cases where your date or time keeps changing from what you’ve previously set it to, your computer is likely syncing with a time server.

3. Why is my computer showing the incorrect time?

You may find your computer clock wrong if the server is unable to be reached or, for a few reasons, is returning an incorrect time. Your watch can also be bad if the zone settings are off. Change internet time server settings if your clock doesn’t seem right.
