Timer

A simple cross-platform tool for calculating elapsed time in C++ program.

Why this?

You may also find that using clock() to calculate the time elapsed is not accurate, like the code bellow

clock_t start = clock();
//do something here
clock_t end = clock();
float millisecs_elapsed = (end - start) / (float) CLOCKS_PER_SEC;

That's because clock() only return the approximate processor time used by the process and the millisecs_elapsed may not be equal to the amount of wall-clock time between end and start

To get the accurate time duration, we need to access the system API. So here comes a Timer for both Linux and Windows.

Timer is tested on

• Windows 7
• Windows 10
• Ubuntu 14.04 LTS / Trusty
• MacOS High Sierra

Use Timer

Just add the TImer.h and Timer.cpp into your project. For how to use, check the example.cpp.

Build Example

Make sure cmake is installed.

For Linux:

mkdir build
cd build
cmake ..
make

For Windows, you can use cmake to generate a Visual Studio project or just create a VS project and add every file then run build.
