class high_resolution_clock;		(C++11 feature)

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.

[edit] Member types

Member type	Definition
rep	arithmetic type representing the number of ticks in the clock's duration
period	an 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>

[edit] Member constants

is_steady	indicates if the clock is monotonous (public static member constant)

[edit] Member functions

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

[edit] See also

system_clock (C++11)	wall clock time from the system-wide realtime clock (class)
steady_clock (C++11)	monotonic clock that will never be adjusted (class)
