constexpr auto operator <=> ( const std:: chrono :: leap_second & x,

const std:: chrono :: sys_time < Duration > & y ) noexcept ;
(12) (since C++20)

Compares the date and time represented by the objects x and y .

Return type of (12) is deduced from x. date ( ) <=> y , and hence the three-way comparison result type of std::chrono::seconds and Duration .

The != operator is synthesized from operator== .

Return value

1) x. date ( ) == y. date ( )
2) x. date ( ) <=> y. date ( )
3) x. date ( ) == y
4) x. date ( ) < y
5) x < y. date ( )
6) x. date ( ) > y
7) x > y. date ( )
8) x. date ( ) <= y
9) x <= y. date ( )
10) x. date ( ) >= y
11) x >= y. date ( )
12) x. date ( ) <=> y
