std::chrono::time_point<Clock,Duration>::operator++, std::chrono::time_point<Clock,Duration>::operator--

constexpr time_point& operator++();
(1) (since C++20)
constexpr time_point operator++(int);
(2) (since C++20)
constexpr time_point& operator--();
(3) (since C++20)
constexpr time_point operator--(int);
(4) (since C++20)

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_--);



Return value

1,3) a reference to this time_point after modification
2,4) a copy of the time_point made before modification
