Converts a CDF TT2000 value to a CDF EPOCH

.. note::
    Although TT2000 values support leapseconds, CDF EPOCH values
    do not. Times during leapseconds are rounded up to beginning
    of the next day.


Parameters
==========
tt2000 : int
    TT2000 value from CDF

Raises
======
EpochError : if input invalid

Returns
=======
out : double
    EPOCH corresponding to the TT2000 input time
