I think that test is wrong, a duration is only constexpr_default_constructible
if the rep type has a default-constructor, but std::chrono::seconds uses a
scalar rep.
I think the test should use something like this to check duration is
constexpr-default-constructible:
struct Seconds {
constexpr Seconds() = default;
std::chrono::seconds s{};
};
test1.operator()<std::chrono::duration<Seconds>>();
