If you want to sync the Cisco device's time, you can use the following command in global configuration mode.
The code is as follows:

NTP (Network Time Protocol) is by David L. professor Mills proposed in 1985 that in addition to estimating the round-trip latency of packets on the network, it can also independently estimate the Computer Clock Deviation, so as to achieve high precision computer calibration on the network, it is a communication protocol designed to enable different machines to maintain the same time on the Internet. A Time Server
NetworkTimeProtocol (NTP, Network Time Protocol) is used to synchronize all of its client clock services. The NTP server uses the local system Network Time Protocol (NTP, Network Time Protocol) to synchronize all of its client clock services. The NTP
Many of us have already used Cisco routers quite well. However, in the face of the NTP time synchronization server configuration, we may not all know about it. Here we will introduce it to you.
