Time-Sync is described as 'Freeware software to synchronize the time of your system. The features of the software are:' and is an app in the os & utilities category. There are more than 10 alternatives to Time-Sync for Windows and Linux. The best Time-Sync alternative is NetTime, which is both free and Open Source. Other great apps like Time-Sync are Chrony, Atomic Clock Time Synchronizer, Network Time Protocol daemon and Meinberg NTP.

Chrony is a pair of programs which are used to maintain the accuracy of the system clock on a computer. The two programs are called chronyd and chronyc.

Atomic Clock Time Synchronizer is a useful and handy utility to keep your PC clock accurate. It periodically checks and synchronizes your computer clock with NIST atomic time servers, or synchronizes time between computers.


The Network Time Protocol daemon (ntpd) is an operating system daemon program that maintains the system time in synchronization with time servers using the Network Time Protocol (NTP). This package is the official reference implementation of the NTP protocol.
NTP client and server download for different operating systems. GUI setup program, full HTML documentation, OpenSSL (Version 0.9.8l) DLL. The installer has been successfully tested on a Preview version of Windows 8 as well.

TimeSync gets the current time from a NIST server, and adjusts the PC clock if necessary. Accuracy is usually within a second. Time and date are displayed according to the users regional settings.


Desktop Atomic Clock is an atomic clock time sync software designed to keep your computer clock always accurate by synchronizing it with an atomic clock NTP server over the Internet. You can choose to sync the time automatically or to use the manual mode.


Neutron is a very simple and small time synchronizing program that retrieves the accurate time from one of several specialized time servers on the Internet. Once the network time has been retrieved the program can set your computers clock to match it.

AboutTime is a superior source of time for your computer. As a time client, it will acquire time from the Internet with great accuracy, and as a server it will provide four kinds of time signals to other computers on your local network.


Advanced Time Synchronizer is a PC clock synchronizer. It works with time servers on the Internet, supports three time synchronization protocols, proxy servers, auto-dialing and more. Advanced Time Synchronizer connects to all the servers in the list one by one until either the...




Atomic Clock Sync utility can help you optimize how often Windows references an atomic clock server, such as the atomic clock servers operated by the National Institute of Standards and Technology (NIST) in the United States.



It's the best and most accurate time synchronization software. It can even improve the accuracy of rtc and system clocks with no other time source available than a wristwatch or a sun dial.
