[LEAPSECS] temporal turf wars

[Steve Allen]

An interesting NIST document from 2000 gives insight into the turf wars
about precision time scales.

http://tf.nist.gov/general/pdf/1429.pdf

The document makes it clear that GPS time was never designed to follow
UTC(USNO) (and by implication, TAI).

The document also clarifies the distinction between (raw) GPS time and
GPS time corrected by the offset given in subframe 4 page 18.

The document also coins the term UTC(GPS) with very interesting
footnotes disclaiming the validity of the use of such a term.
