If your system is standalone, the default sync interval for system time is 604800 seconds (7 days). If you are in a domain environment, the default sync interval is 3600 seconds (0.04166667 days). If you are using XP Pro, you can adjust your settings using Group Policy editor (GPedit - Administrative Templates\System\Windows Time Service\Time Providers) or you can adjust things through a registry edit (works for any version of XP).
The synchronization type is NT5DS. The time service synchronizes from the domain hierarchy and the time service accepts all time changes. Because NT5DS accepts any time change without considering the time offset, it is very important to set up a reliable forest root time source in the time sync subnet.he default is 5 minutes. You can also turn off the Time Service tool. Then, you can install a third-party time service. The purpose of the Time Service tool is to make sure that all the computers in an organization that are running Microsoft Windows 2000 or later versions of Windows operating systems use a common time.
