 (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
