std::chrono::high_resolution_clock: std::chrono::high_resolution_clock

NAME

std::chrono::high_resolution_clock - std::chrono::high_resolution_clock

Synopsis


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.

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>

Member constants


constexpr bool is_steady 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, otherwise false
                         (public static member constant)
[static]

Member functions


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