Electronic clocks control critical functions in many applications. However, clocks are often designed for low cost rather than keeping accurate time. Even fairly accurate computer clocks are likely to vary due to manufacturing issues, changes in temperature, electric and magnetic interference, the age of the quartz crystal, or even system load.

In time-related applications, it is important to determine which clock will be used as the primary time reference for all other clocks, and then to understand how to transfer the time from that reference clock to the others. 
 
The best solution is to use a special timing reference clock, or master clock. What is a master clock? What industries, applications, and common uses are there for master clocks?

Time is critical for transactions across computer networks. Many events on the network need accurate time to initiate and control processes, and complete transactions such as authentication. Accurate time for time stamps and log files is also very important for billing systems, network diagnostics, digital forensics, high-reliability databases and process analysis.

Network cybersecurity is top of mind these days for both government agencies and commercial enterprise. As the heart of network synchronization, time and frequency systems should include a standard suite of security features that give network administrators confidence in the cybersecurity protocols of their time servers.
