How to Add or Change Internet Time Servers in Windows 11

This article explains how to add, change or remove Internet Time Servers in Windows 11.

By default, your Windows computer automatically syncs its clock with the internet server, typically Microsoft Internet servers, once a week. The clock records events and times associated with those events whenever you create or modify files.

Your PC also uses Internet Time Servers to keep accurate time and update its timezone and daylight save time when available.

Windows includes a list of available Internet time servers you can choose from by default. However, you can also add or remove existing time servers at any time.

The steps below show you how to do that in Windows 11.
