On Windows 10, you’ve been able to synchronize the clock to the correct date and time on your device for a long time, but the settings were buried in Control Panel.
Starting with Windows 10 version 1903 (April 2019 Update), the Settings app is adding the option to sync the clock using the Time & Language settings, which can come in handy when the time server has been disabled, or the clock is showing the time accurately.
How to sync date and time manually using Settings
To synchronize your clock using the Settings app, use these steps:
Click on Time & Language.
Click on Date & time.
Under “Synchronize your clock,” click the Sync now button.Quick Tip: If the process fails, wait a few seconds, and try again.
Once you’ve completed the steps, Windows 10 will synchronize the clock (including the date) with the time server currently configured on device. You can also see when the synchronization took place, and at which time a server was used.
If you don’t see this option, it’s because you’re not using the supported version of Windows 10 that supports this feature in the Settings app. This feature is available starting with Windows 10 version 1903 (April 2019 Update).
