Introduction to NTP:

1. NTP is a network protocol used to synchronize the time across devices in a computer network.

2. An NTP server (Network Time Protocol Server) is a server that provides accurate time information and enables time synchronization.

3. NTP servers obtain accurate time by connecting to reliable time sources (such as atomic clocks or GPS signals) and transmit this time to clients connected to the server.

4. The NTP server addresses collected by the above tools are sourced from the internet; please test them before use.
