How to Add and Remove Internet Time Servers in Windows


Your PC's clock is used to record the time whenever you create or modify files on your PC. You can change the clock's time and time zone.

You can synchronize your PC's clock with an Internet time server. This means that the clock on your PC is updated to match the clock on the time server, which can help ensure that the clock's time on your PC is accurate. Your clock is typically automatically updated once a week and needs to be connected to the Internet for the synchronization to occur.

Windows includes a list of available Internet time servers to select from by default, but you can add and remove time servers you want from this list.

This tutorial will show you how to add and remove Internet time servers (NTP server) used to synchronize your clock in Windows 7, Windows 8, and Windows 10.

You must be signed in as an administrator to add or remove an Internet time server.
