Modifies the point in time *this represents by one tick of the duration.

If d_ is a member variable holding the duration (i.e., time since epoch) of this time_point object,

1) Equivalent to ++d_; return *this;

2) Equivalent to return time_point(d_++)

3) Equivalent to --d_; return *this;

4) Equivalent to return time_point(d_--);

Parameters

(none)

Return value

1,3) a reference to this time_point after modification

2,4) a copy of the time_point made before modification
