does the navy maitain the national clock for time standards?

Answer 1

The Naval Observatory maintains one of the atomic clocks and makes it available for use through a web site and dial in phone numbers. Remember the importance of exact time was critical in navigation. Many of the important advances in time keeping were the result of navy requirements for accuracy.

Answer 2

National Bureau of Standards maintains time standards which are broadcast every five minutes by a radio station WWV which you can pick up on most short wave bands.

The atomic clock in Colorado broadcast a signal that will correct clocks set up to receive it.

Generally, however, the Navy calls me about 7AM every day and asks me what time it is - I have a timex.

"Mary had a little watch,
she swallowed it one day.
She took a dose of oil
to pass the time away.
The oil did not work,
The time did not pass,
So if you want to know what time it is,
Look up Mary's uncle - he has a Timex."
