[LEAPSECS] "old UTC" and "new UTC"

[Steve Allen]

A piece of history from the JPL DSN operations
http://ipnpr.jpl.nasa.gov/progress_report2/VIII/VIIIT.PDF
gives a view into the level of nomenclature confusion that happened
around 1972.  At that date no CCIR document had used the term "UTC".

Not only does it use "old UTC" and "new UTC", but it also
makes "new UTC" synonymous with "IAT" and "A.1", and to
the relevant precision all of them interchanged with "GMT".

There is also the interesting assertion that in the US the NBS was
responsible for frequency and USNO was responsible for time.
