Network Time Protocol (NTP) presents an unique ability for companies to synchronize the clocks of all the systems within the company. Time synchronization is important for many reasons ranging from application time stamps to security to proper log entries. When an organization’s systems all maintain different clock times, it becomes very difficult from a troubleshooting standpoint to determine when and under what conditions a particular event might be occurring.
NTP provides an easy way to ensure that all systems will maintain the correct time which in turn can greatly simplify the burden on administrators/tech support.
