Rich comparison operator ‘>’.
Comparing two UTCDateTime object will always compare timestamps rounded to a precision of 6 digits by default.
>>> t1 = UTCDateTime(123.000000099)
>>> t2 = UTCDateTime(123.000000012)
>>> t1 > t2
False
But the actual timestamp differ
>>> t1.timestamp > t2.timestamp
True
Resetting the precision changes the behaviour of the operator
>>> t1.precision = 11
>>> t1 > t2
True
