(NDS) technology on your network.
Time synchronization is important to the operation of NDS technology because it establishes the order of events. It is a method of ensuring that all servers in a Directory tree report the same time.
Clocks in computers can deviate slightly, resulting in different times on different servers. Time synchronization corrects these deviations so that all servers in a Directory tree report the same time and provide a time stamp to order NDS events.
For most situations, the default settings for time synchronization are sufficient. However, as you understand the different types of time servers and the process of synchronization, you might decide that your environment will benefit from customization.
