#include <CElapsedTime>
class CElapsedTime
{
public:
CElapsedTime();
void start();
double measure() const;
};
This class supports POSIX-.1-2001 conforming sub second interval
measurement.
Note that the actual resolution of this timing is dependent on the
resolution of the underlying system clock used by
gettimeofday(3).
Constructing the object or invoking start
on a constructed object sets a start time. Subsequent calls to
measure return the elapsed time since
that start time in double precision seconds.
