What are the main functions of a Grandmaster Clock in a network?

A PTP Grandmaster Clock is a very important clock in a network. Its main function is to give the exact time to all other devices in the network. This helps every device to work together correctly. It sends time signals to other clocks, so they are all synchronized. This is very important for systems that need precise timing, like computers, phones, or power grids. Another function is to decide which clock in the network is the most accurate if there are many clocks. It also helps keep the network running smoothly by preventing time errors. In short, the Grandmaster Clock keeps time accurate, shares it with all devices, and makes sure the whole network works together properly.
