Why is the Niagara G3 Time Sync Service not working with time.nist.gov?

Issue

Why is the Niagara G3 Time Sync Service not working with time.nist.gov?

Product Line

TAC I/A Series

Environment

  • Niagara G3
  • time.nist.gov

Cause

As of April 2007 the server time.nist.gov no longer responds to requests for time in the "Time Protocol" format defined in RFC-868.

Resolution

As an alternative, try time-a.nist.gov or time-b.nist.gov

As of April 2007 the server time.nist.gov no longer responds to requests for time in the "Time Protocol" format defined in RFC-868.

All of the other NIST servers (except for time-nw.nist.gov) will continue to respond to requests to either tcp or udp port 37 for time in the format specified in RFC-868.

"Time Protocol" used by the TimeSyncService has been superseded by a more sophisticated and more accurate one known as "Network Time Protocol" (NTP for short) defined in RFC-1305

The newer protocol is supported in Niagara G3 version 3.4 and newer and it is configured through the platform service of the station.
