std::chrono::hh_mm_ss
Defined in header <chrono>
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.

Member constants

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)

Member types

Member functions
