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
