template <class Clock, class Duration = typename Clock::duration>  class time_point;
Time point
A time_point object expresses a point in time relative to a clock's epoch.

Internally, the object stores an object of a duration type, and uses the Clock type as a reference for its epoch.

模板参数

Clock
A clock class, such as system_clock, steady_clock, high_resolution_clock or a custom clock class.
Duration
A duration type.
