NIST-80 Time Server

Beagle Software maintains a timeserver that communicates using the NIST-80 protocol (clockwatch-nist.com). Support for the NIST-80 protocol is a ClockWatch exclusive and began in version 2.2

Major Uses:

When other protocols are blocked by firewalls
Firewalls often restrict all communication over the ports normally used by public timeservers. If it impractical to reconfigure the firewall, then use the NIST-80 protocol that communicates over tcp port 80, the same port used for web communication. Beagle Software maintains an NIST-80 timeserver. It can be selected from the timeserver directory list within ClockWatch. (see Options->Timeserver, Directory)


NIST-80 time setting format
 Communicates via TCP/IP on port 80. After a setting is made, the time string used in the setting is displayed in the timeserver log window. ClockWatch translates this string. All times from NIST-80 are in UTC. This time string is made up of a series of fields arranged end to end.

Format headings, with an actual sample time string below it:

Host       YYMMDD  HHMMSS  
beaglesoft  02-03-06 22:01:22

Host - This identifies the host responding to the request, in this case Beagle Software.

YYMMDD HHMMSS - The next 6 values give the Coordinated Universal date and time (formerly called Greenwich Mean Time) as year, month, day, hour, minute and second.
