common_type

hash<std::chrono::time_point> (C++26)

 

template< class Clock, class Duration1, class Duration2 > struct common_type<std::chrono::time_point<Clock, Duration1>, std::chrono::time_point<Clock, Duration2>>;		(since C++11)

Exposes the type named type, which is the common type of two std::chrono::time_points.

Member types

Member type	Definition
type	std::chrono::time_point<Clock, typename std::common_type<Duration1, Duration2>::type>

Notes

The common type of two std::chrono::time_point types is a std::chrono::time_point with the same clock as the two types and the std::common_type of their durations.
