Keeping System Clocks and System Times Synchronized

SureSync can be used to synchronize files all over the world and across multiple time zones without any issue. This is due to the fact that the time and date stamp on a file is stored in Universal Coordinated Time (UTC), also known as Greenwich Mean Time (GMT). The displayed time is then adjusted by the time settings configured on the particular computer in question. SureSync uses the UTC time to ensure that time zone changes are not an issue. For example, if you have a machine that is located in California and a machine that is located in New York then you have a machine running in the Pacific Time Zone and one running in the Eastern Time Zone. SureSync can synchronize these files without any problem because the application looks at the UTC time stamp on the file, not the adjusted time stamp that is shown to the user through the operating systems user interface.
However, the clocks must be synchronized within 2 minutes of each other to ensure accurate results. In our example, assume that it is 8:30AM in California and the server located there is configured as such. That means the clock on the machine in New York in the Eastern Time Zone should have a clock which reads 11:30 AM. These two clocks will compare identically in UTC time. Now assume that the machine in New York is incorrectly configured to 11:15AM. This clock is now 15 minutes off of the actual time and the UTC time stamp on the file is not going to compare equally either.
Making sure that the clocks on the machines throughout your enterprise have equal times will help to ensure proper SureSync operation. SureSync will warn you if the clocks on any of the machines involved in a synchronization are off by more than the acceptable amount.

Windows Time Service

Microsoft has made it easy to keep all of the system clocks in your enterprise synchronized through the use of the Windows Time Service. Please consult the links below for further details on the Windows Time Service and how to configure it for your network(s).
There is additional documentation available at Microsoft's TechNet site by searching for the keywords Windows Time Service if you would like additional material on this topic.

Third Party Clock Synchronization Tools

There are many free or shareware clock synchronization tools available which can be used to keep the clocks on your computers synchronized if you decide not to use the Windows Time Service.
