Most of these clocks are set by hand to within a minute or two of actual time and are rarely checked after that. Many of these clocks are maintained by a battery-backed, clock-calendar device that may drift as much as a second per day.

Having any sort of meaningful time synchronization is impossible if such clocks are allowed to run on their own. The Importance of Time Synchronization for Your Network In modern computer networks time synchronization is critical because every aspect of managing, securing, planning, and debugging a network involves determining when events happen.

Time also provides the only frame of reference between all devices on the network. Without synchronized time, accurately correlating log files between these devices is difficult, even impossible. Following are just a few specific reasons: Tracking security breaches, network usage, or problems affecting a large number of components can be nearly impossible if timestamps in logs are inaccurate.
