Detailed Description

The timer allows to measure time with a precision of about 30us on Linux systems and ??? on windows systems.

The maximum time that can be measured with this function is 1 day (86.4E+09 microseconds). To measure longer time intervalls use the standard time() function.

Note that this function returns the Wall-Clock time and not the CPU-Time.

Example:

      lti::timer chron;

      chron.start();

      // do something

      chron.stop();

      std::cout << "something takes " << chron.getTime() << " microseconds\n";
