NTP server: Network time Protocol (NTP) is a protocol used to synchronize the timing of a computer, which allows the computer to synchronize its servers or clock sources (such as quartz clocks, GPS, etc.) It provides high-precision time correction (less than 1 milliseconds on LAN versus standard, dozens of MS on WAN) and can be referred to as a cryptographic ackn

1. Introduction to NTPNTP, Network Time Protocol, is a protocol that is used to synchronize the time of each computer in a network. Its purpose is to synchronize the computer clock to the World coordinated UTC, its accuracy in the LAN up to 0.1ms, in most places on the Internet its accuracy can reach 1-50ms.NTP servers provide time synchronization services using the NTP protocol.2. NTP

. Regardless of the time that we want to sync the system through any channel, the provider will usually give only the utc+0 time value and not the time zone (because it doesn't know where you are). So when we set the system time, it's the first thing to do # date Thu Oct 11:22:45 EDT 2013 If the time zone is found to be incorrect, the method of modification is shown in Appendix 1 2.
