Performs add and subtract operations involving a time_point.

1-2) Applies the offset d to pt. Effectively pt += d is performed.
3) Applies the offset d to pt in negative direction. Effectively pt += (-d) 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

(none).
