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
(none).
