The std::chrono::time_point class template represents
a point in time, as measured by a particular clock. It is specified as
a duration since the epoch of that particular clock.
The template parameter Clock
identifies the clock (each distinct clock must have a unique type), whilst
the Duration template parameter
is the type to use for measuring the duration since the epoch, and must
be an instantiation of the std::chrono::duration class template. The
Duration defaults to the
default duration type of the Clock.
template < class Clock, class Duration = typename Clock::duration> class time_point { public: typedef Clock clock; typedef Duration duration; typedef typename duration::rep rep; typedef typename duration::period period; time_point(); explicit time_point(const duration& d); template <class Duration2> time_point(const time_point<clock, Duration2>& t); duration time_since_epoch() const; time_point& operator+=(const duration& d); time_point& operator-=(const duration& d); static constexpr time_point min(); static constexpr time_point max(); };
