constexpr std::chrono::minutes minutes() const noexcept;	(3)
constexpr std::chrono::seconds seconds() const noexcept;	(4)
constexpr precision subseconds() const noexcept;	(5)

Obtains the components of the stored "broken down" time.

Return value

Let d be the represented duration:

1) true if d is negative, false otherwise.

2) std::chrono::duration_cast<std::chrono::hours>(abs(d))

3) std::chrono::duration_cast<std::chrono::minutes>(abs(d) - hours())

4) std::chrono::duration_cast<std::chrono::seconds>(abs(d) - hours() - minutes())

5) abs(d) - hours() - minutes() - seconds() if std::chrono::treat_as_floating_point_v<precision::rep> is true; otherwise std::chrono::duration_cast<precision>(abs(d) - hours() - minutes() - seconds()).
