<p>This operation create a new UTO object representing the time in the target
object added to current time (UTC). The time base is
<em>15 october 1582 00:00</em>. Comparing two time objects which use
different time base is, by obvious reasons, pointless.
Raises DATA_CONVERSION if causes an overflow. This operation is only useful
if the target object represents a relative time.</p>

the target object is always used as the first parameter in the
comparison, i.e., if the target object's time is larger
'TCGreaterThan' will be returned.</item>
<item>'IntervalC' - also takes the inaccuracy into consideration, i.e.,
if the two objects interval overlaps 'TCIndeterminate' is returned,
otherwise the as for 'MidC'.</item>
