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.
My Favorite Network Time Synchronizer For Windows:
Magitime is one of my favorite time synchronization software for PC. Apart from time synchronization, it lets you track LAN and other networks, detect dial-up connections, schedule reminders, track internet expenses, etc.

To use this net time sync tool, you just need to launch the software, specify the time server, and click on Sync Now button. You may require to use it with time.ien.it, cuckoo.nevada.edu servers to synchronize time. Thus, it is one of the simplest to use software for time synchronization. Home Page Download Page
Coopoint Atomic Clock Sync
Coopoint Atomic Clock Sync is another free server time synchronization software for Windows. The software interface is kept very simple and displays information about server time, local time, their difference, and also time zone. You can change time zone as per your requirement.
In order to synchronize time of your PC to the server, you need to click on synchronize button icon given in the lower part of the interface. Also, by clicking on Change time zone option, you can manually set date and time, time zone, specify additional clocks to see time for other time zones, and synchronize your PC to internet time using time.windows.com server. You can see time for other time zones (specified using additional clocks), by hovering over or clicking on the taskbar clock. Home Page Download Page
Neutron is another good software to synchronize PC time to server. You need to run it with administrator privilege in order to make corrections to system date and time.
As you launch this software, you can see the current system time. Now, you can click on Get atomic time button to get atomic time. In order to adjust system clock, you need to click on Synchronize button and wait for just a few seconds to allow the software to establish connection to the server and make appropriate corrections.
