Header only Timer class based on C++11 std::chrono. Simply download the Timer.hpp file and include it where required.
#include <iostream>
#include <thread>
#include <chrono>
#include "Timer.hpp"
int main() {
Timer timer;
timer.start();
std::this_thread::sleep_for(std::chrono::seconds(3)); // sleep for 3 seconds
std::cout << "microseconds elapsed: " << timer.microseconds_elapsed() << "\n";
std::cout << "milliseconds elapsed: " << timer.milliseconds_elapsed() << "\n";
std::cout << "seconds elapsed: " << timer.seconds_elapsed() << "\n";
return 0;
};
Timer has the following methods
| Method | Description |
|---|---|
| start() | Start the timer |
| reset() | Reset the timer (alias for start) |
| nanoseconds_elapsed() | Returns nanoseconds elapsed since timer started |
| microseconds_elapsed() | Returns microseconds elapsed since timer started |
| milliseconds_elapsed() | Returns milliseconds elapsed since timer started |
| seconds_elapsed() | Returns seconds elapsed since timer started |
| minutes_elapsed() | Returns minutes elapsed since timer started |
| hours_elapsed() | Returns hours elapsed since timer started |
The return type of all xxx_elapsed() functions is unsigned long.
Be careful with using nanoseconds and microseconds as they can easily overflow.
