[time-nuts] Where do people get the time?

[Thomas D. Erb]

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.
