Detailed Description

a Class to measure passing time.

The class computes passing time by counting the number of ticks per second. That is, the following code computes the execution time in seconds:

tm.start();
// do something ...
tm.stop();
std::cout << tm.getTimeSec();

It is also possible to compute the average time over multiple runs:

for (int i = 0; i < 100; i++)
{
tm.start();
// do something ...
tm.stop();
}
double average_time = tm.getTimeSec() / tm.getCounter();
std::cout << "Average time in second per iteration is: " << average_time << std::endl;
