The system will try finding the closest available servers for you. If you distribute software or equipment that uses NTP, please see our information for vendors. The Network Time Protocols working group is focused on enhancing existing network time synchronization protocols, such as the Network Time Protocol (NTP), and specifying new network-time-related protocols or extensions for purposes that the existing protocols are not well suited to address. NTP was first defined in the IETF in RFC 958 in 1985.The NTP subnet operates with a hierarchy of levels, where each level is assigned a number called the stratum. Stratum 1 (primary) servers at the lowest level are directly synchronized to national time services via satellite, radio or telephone modem. Stratum 2 (secondary) servers at the next higher level are synchronized to stratum 1 …In most cases it's best to use pool.ntp.org to find an NTP server (or 0.pool.ntp.org, 1.pool.ntp.org, etc if you need multiple server names).
