Performs add and subtract operations involving a time_point.

1-2) Applies the offset d to pt. Effectively pt += dur is performed.

3) Applies the offset d to pt in negative direction. Effectively pt += (-dur) is performed.

4) Computes the difference between pt_lhs and pt_rhs.

Parameters

pt	-	a time point to apply the offset to
d	-	a time offset
pt_lhs, pt_rhs	-	time points to extract difference from

Return value

1-3) The time point that resulted from applying the offset d.

4) The duration between the time points.

Exceptions
