years ago I was out a large clock installation in NYC - written on the wall was a note - before noon tune to a specific shortwave frequency to listen to the noon type signal.
Western Union used to distribute time over their telegraph network for a small fee - in connection with the Self Winding Clock Company The power company (still does) keeps line frequency accurate to a time standard. Henry Warren got this standardized - I believe Tesla proposed it. Cell phone towers all have GPS receivers - there are ways to get time off them. We now use GPS receivers everywhere you can get a nmea sentences that has UTC time. Thomas D.
