SERVICES OF NTP SERVERS

NTP 1VNIIFTRI provides free access to its servers for time scale synchronization using NTP protocol. The NTP servers operated by VNIIFTRI consist of a group of four stratum-1 servers connected to the national primary time standard of the Russian Federation and four stratum-1 servers connected to secondary standards, and also one stratum-2 server synchronized to the main group of servers. All the servers provide access using NTPv4 IPv4 protocol in keeping with RFC-5905.

The accuracy of synchronization provided by NTPv4 is in the order of a few tens of milliseconds when synchronizing over the Internet.

Support for NTP version 4 is available for most operating systems, for instance::
