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
