- Shells and USNO
-
-
- The documentation for version 1.05 of USNO mentions a "reverse mode", but
- doesn't really explain what it's for. That's what this document is about.
-
- The "reverse mode" in USNO allows USNO to be used as a "shell" under
- version 4.50 of the SEAdog mailer. As currently implemented, the shell
- signal must be a capital "T" (decimal value 84). Hence, the appropriate
- SHELL command in the SEAdog configuration file would be:
-
- shell 84 usno /r30
-
- This would allow a calling USNO to trigger the local copy of USNO in
- reverse mode, and would allow up to thirty seconds for the caller to set
- his clock. This also assumes that the local system has its clock set to
- Greenwich Mean Time, which is probably not the case. A time zone should be
- specified to correct from local time to universal time.
-
- For example, the SEAdog system at 520/1015 runs on Eastern Standard Time,
- so in its CONFIG.DOG file it has a SHELL statement of:
-
- shell 84 usno EST /r30
-
-
- As of this writing, the phone number for 520/1015 is (201) 473-8522, so a
- remote system in Clifton, NJ wishing to set its clock from 520/1015 would
- use a command of the form:
-
- usno EST /p473-8522
-
- Similarly, a system in Colorado wishing to set its clock to Mountain
- Daylight Time from 520/1015 would use a command of the form:
-
- usno MDT /p1-201-473-8522
