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_--);.

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.

Example

operator++operator++(int)operator--operator--(int)	increments or decrements the tick count (public member function of std::chrono::duration<Rep,Period>)
operator+=operator-=	modifies the time point by the given duration (public member function)
operator+operator- (C++11)	performs add and subtract operations involving a time point (function template)
