Stacktrace
 
 
 
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.
