Is all that stuff just a reinvention of the wheel? What's the value add over DateTime and the zillions of other date/time modules already on CPAN?
I have to admit I haven't really looked at your code in depth but I
don't see how you can accurately be calculating TT/etc. without doing an
interpolation of IERS data.
If your interested in looking a working implementation of this I have one
in C as part of this library:
http://pan-starrs.ifa.hawaii.edu/project/IPP/software/pslib/
The relevant functions are documented here:

(caution: not well tested)
