From cppreference.com
| 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 [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) |
Member functions
| [static] |
returns a std::chrono::time_point representing the current value of the clock (public static member function) |
