15 Best Free Network Time Synchronizer For Windows

Here is a list of best free network time synchronizer for Windows. These software come in handy to synchronize the time of your PC to a server. You can use these net time sync tools when Windows default synchronization feature fails. These software use SNTP (Simple Network Time Protocol), UDP (User Datagram Protocol), TCP (Transmission Control Protocol), RFC868, etc. time protocols. Also, these software let you define synchronization interval to check out time errors and auto correct them. While some of these software perform network time synchronization as soon as you launch them, many can do the same in both, automatic and manual modes.

Most of these net time sync tools come with some built-in servers to synchronize PC time to them. You can select a server to synchronize time to it or add a new server. Also, these software switch to other servers to synchronize PC time in case they lose connection with the current one.

Note: Most of these network time synchronizer need administrative privilege to make changes to system clock.
