Class for computing wall-clock times.
class tick_count;
#include "tbb/tick_count.h"
A tick_count is an absolute timestamp. Two tick_count objects may be subtracted to compute a relative time tick_count::interval_t, which can be converted to seconds.
Example
using namespace tbb;
void Foo() {
tick_count t0 = tick_count::now();
...action being timed...
tick_count t1 = tick_count::now();
printf("time for action = %g seconds\n", (t1-t0).seconds() );
}
namespace tbb {
class tick_count {
public:
class interval_t;
static tick_count now();
static double resolution();
};
tick_count::interval_t operator-( const tick_count& t1,
const tick_count& t0 );
} // tbb
