VTScada and Time Synchronization

The following information is of concern only if you are not already maintaining time synchronization between servers and if it is important to your operation to maintain synchronization of clocks between servers.

VTScada includes code that will maintain time synchronization between networked servers. Due to security settings in Windows, the Time Synchronization Service will work only if VTScada is started with an account that has the SE_SYSTEMTIME_NAME security flag set. The Windows Administrator account will generally have this privilege, but you can also set it for other user accounts.

To do so, you must set the user privilege, "Change the System Time" to true using the Windows Group Policy Management Editor. Please refer to Microsoft’s documentation for instructions on using this system tool.
