Wharton 5000 series Ethernet Time Server
Ethernet - time reference synchronisation

NTP/SNTP The 5000 series Time Server can be time synchronised from a remote NTP time server located on your TCP/IP network.

Ethernet - time server options

All models have a 10/100Base-t Ethernet interface to allow the unit to act as an NTP Time Server on a TCP/IP network. 5600 network time servers are fitted with dual 10/100Base-t Ethernet interfaces to provide additional system redundancy and expansion capability.

The following network protocols are supported:

  • NTP - Network Time Protocol v2, v3 and v4 clients are supported in both unicast and broadcast modes of operation. (RFC1305 & RFC1119).
  • SNTP - Simple Network Time Protocol v3 and v4 clients are supported in both unicast and broadcast modes of operation. (RFC2030 & RFC1769).
  • TIME protocol (RFC868) is supported in UDP and TCP mode.
  • DAYTIME protocol (RFC867) is support in UDP and TCP mode.
More information on Network Time Protocol

Network Time Protocol (NTP) is one of the oldest Internet protocols in use and was originally designed in 1985 by David L. Mills of the University of Delaware. NTP is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks.

NTP is intended to synchronize all participating computers to within a few milliseconds of Coordinated Universal Time (UTC). It uses a modified version of Marzullo's algorithm to select accurate time servers and is designed to mitigate the effects of variable network latency. NTP can achieve better than one millisecond accuracy in local area networks under ideal conditions.
