Converts a CDF epoch16 value to TT2000

.. note::
    Because TT2000 does not support picoseconds, the picoseconds
    value in epoch is ignored (i.e., truncated.)

Parameters
==========
epoch0 : float
    epoch16 value from CDF, first half
epoch1 : float
    epoch16 value from CDF, second half

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

Returns
=======
out : long
    TT2000 corresponding to epoch.
