[time-nuts] Re: What everyday uses are there for accurate clocks?

[RONALD SMITH]

Synchronisation of ALL telecom systems using TDM.

Maybe synchronisation of VLBI radio-astronomy systems too, keeping 
outputs of radio-telescopes on opposite sides of the planet in step. 
That's not my field, only a guess.

Subject: [time-nuts] What everyday uses are there for accurate clocks?
I mentioned to someone the other day that I owned an HP GPS time and
frequency standard. He asked me a simple question, but one I didn’t know
the answer to.

Apart from GPS, what in the daily lives of the general public need the 
sort
of accuracy one can get from time-nut grade clocks? I believe some
financial transactions is one application, and the cellular phone system
another. Are there others?
I found a few links
