class steady_clock; | (since C++11) |
Class std::chrono::steady_clock represents a monotonic clock. The time points of this clock cannot decrease as physical time moves forward. This clock is not related to wall clock time (for example, it can be time since last reboot), and is most suitable for measuring intervals.
std::chrono::steady_clock meets the requirements of TrivialClock.
| 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> |
| constexpr bool is_steady
[static]
| steady clock flag, always true (public static member constant) |
| [static]
| returns a time_point representing the current value of the clock (public static member function) |
| (C++11)
| wall clock time from the system-wide realtime clock (class) |
| (C++11)
| the clock with the shortest tick period available (class) |
