std::chrono::high_resolution_clock

Member functions

high_resolution_clock::now

 

Defined in header <chrono>
class high_resolution_clock;		(since C++11)

Class std::chrono::high_resolution_clock represents the clock with the smallest tick period available on the system. It may be an alias of std::chrono::system_clock or std::chrono::steady_clock, or a third, independent clock.

std::chrono::high_resolution_clock meets the requirements of TrivialClock.

Member types

Member type	Definition
rep	arithmetic type representing the number of ticks in the clock's duration
period	a std::ratio type representing the tick period of the clock, in seconds
duration	std::chrono::duration<rep, period>
time_point	std::chrono::time_point<std::chrono::steady_clock>

Member constants

bool is_steady [static]	true if the time between ticks is constant and calls to now return values that increase monotonically (public static member constant)

Member functions

now [static]	returns a std::chrono::time_point representing the current value of the clock (public static member function)
