Sorry. This is so esoteric in fineness that I cannot restate
from recollection other than it is a minor trim to UT1 which
assures by year workabiity of NO algorithms, including those
once published as "Almanac for Computers". It generally has to
do with achieving 1-arc second accuracy of computations.
Really, I should have not mentioned it at all!

The subject matter is covered in the Astronomical Almanac and
further in "other publications", particularly by Seidleman.
Try http://aa.usno.navy.mil/AA/ and search on dynamic time
and dynamical time for more authoritative information.

Happy New Year to you and all!
