[GreenKeys] Western Union Time

Hi Folks,

Slightly "off topic" but very much Western Union (the folks who had all 
those teletypes) I have a collection of WU clocks.  They were made by the 
Self Winding Clock Co. of NYC.  WU sent a pulse every hour to a solenoid in 
the clock that pulled the minute and second hand straight up.

I wrote to the NIST who opereate WWV et.al. from their time site... 
http://www.time.gov/timezone.cgi?Eastern/d/-5/java  ....asking if there is a 
way to use their web site to get that hourly correction pulse for my clocks. 
Mike Lombardi wrote back that they don't have the 1 KHz correction pulse on 
the internet site that is on WWV et. al. on the hour.

I know some of the nerds on this list talked about having their TTY machines 
print time...so my question is, has anyone the ability to extract a pulse 
from a computer to sense the hourly zeros at the above site?

BTW, Mike (at NIST) asked if I know anything about "radio controlled 
clocks"...which I've never heard of...anyone here that can comment on these?

Thanks,
Lar
