Free synchronize time software for windows

Time Synchronizer adjusts your PC clock with a public time server that uses an atomic clock Time Synchronizer adjusts your PC clock with a public time server that uses an atomic clock.
To automatically start Time Synchronizer every time you boot your system, connect to the time server, synchronize the clock and then quit... Just check the required entries in the configuration box.
If your system clock is very erratic you may want to set it to connect and adjust the clock every 5 or 10 minutes.

Directory Synchronize synchronizes the contents of one directory to another That means you can use Directory Synchronize to backup your data on a regular basis to another PC or another hard drive.
Directory Synchronize can compare (e.g. size, modified-date, ...) and synchronize an unlimitted number of directories and has a detailed logging-function.
Directory Synchronize is the small handy utility you always missed! Directory Synchronize is small, reliable, and fast. And best of all - it is Open Source; released under the GPL you are free to use and distribute it.
You can also use Directory Synchronize to synchronize the data on your laptop with the data on your desktop.
Programmed in real platform independent Java you can use Directory Synchronize on nearly every computer platform including Windows, Linux and Macintosh.
Use the Directory Synchronize GUI for starting, pausing and stopping a synchronization. Or use the GUI to easily create and store a configuration and use the command line to automatically start it every time you boot up your computer.
System requirements:
- Java

Atomic Clock Time Synchronizer is a useful and handy utility to keep your PC clock accurate Atomic Clock Time Synchronizer is an application to keep your PC clock accurate.
It periodically checks and synchronizes your computer clock with NIST atomic time servers, or synchronizes time between computers.
Here are some key features of "Atomic Clock Time Synchronizer":
- Synchronizes time with NIST atomic time servers
- Proxy support: Socks4/Socks4A/Socks5/HTTP
- Supports SNTP (the Simple Network time protocol)
- Supports the TIME protocol
- Can synchronize time with any server running SNTP or TIME protocol
- Periodically checks and synchronizes time at specific interval
- Displays time in either local time or UTC/GMT
- Easy to use and configure
- Nice-looking interface
System requirements:
- 600 megahertz (MHz) Pentium processor, or an AMD Opteron, AMD Athlon64 or AMD Athlon XP processor

It synchronizes your PC clock to the NIST internet servers cmxSyncTime application was designed to synchronize your PC clock time using the NIST internet time servers.
The NIST time is based on atomic oscillators in Boulder, CO. cmxSyncTime can schedule synchronization updates periodically to keep your PC clock accurate.
This is a handy function since PC clocks tend to fade over time loosing or sometimes gaining seconds or minutes eventually.
