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 provided by the implementation. 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.

Contents

[edit] 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::high_resolution_clock>

[edit] Member constants

constexpr bool is_steady
[static]
true if the time between ticks is always constant, i.e. calls to now() return values that increase monotonically even in case of some external clock adjustment
(public static member constant)

[edit] Member functions

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