Helper classes

common_type

 

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

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

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.
