std::chrono::hh_mm_ss<Duration>::hh_mm_ss

constexpr hh_mm_ss() noexcept : hh_mm_ss{Duration::zero()} {}

constexpr explicit hh_mm_ss( Duration d );

Constructs a hh_mm_ss object.

• is_negative() returns d < Duration::zero().
• hours() returns std::chrono::duration_cast<std::chrono::hours>(abs(d)).
• minutes() returns std::chrono::duration_cast<std::chrono::minutes>(abs(d) - hours()).
• seconds() returns
  std::chrono::duration_cast<std::chrono::seconds>(abs(d) - hours() - minutes()).
• subseconds() returns abs(d) - hours() - minutes() - seconds() if std::chrono::treat_as_floating_point_v<precision::rep> is true; otherwise it returns std::chrono::duration_cast<precision>(abs(d) - hours() - minutes() - seconds()).

Parameters

Example

#include <chrono>
#include <print>
 
int main()
{
    std::println("Default constructor: {}", std::chrono::hh_mm_ss<std::chrono::minutes>{});

    std::chrono::time_point now = std::chrono::system_clock::now();
    std::chrono::hh_mm_ss time_of_day{now - std::chrono::floor<std::chrono::days>(now)};
    std::println("The time of day is: {}", time_of_day);
}

Default constructor: 00:00:00
The time of day is: 12:13:14.151617189
