template< class Duration > class hh_mm_ss; | (since C++20) |
The class template hh_mm_ss splits a std::chrono::duration into a "broken down" time such as hours:minutes:seconds, with the precision of the split determined by the Duration template parameter. It is primarily a formatting tool.
Duration must be a specialization of std::chrono::duration, otherwise the program is ill-formed.
| constexpr unsigned fractional_width
[static] | the smallest possible integer in the range [0, 18] such that precision (see below) will exactly represent the value of Duration{1}, or 6 if there's no such integer (public static member constant) |

|
obtains the stored std::chrono::duration (public member function) |
|
(C++20) | outputs a hh_mm_ss into a stream (function template) |
|
(C++20) | specialization of std::formatter that formats a hh_mm_ss according to the provided format (class template specialization) |
