Timer

Definition

Returns the actual time in milliseconds.

Examples

The following example uses the clock subroutine to get the actual time in milliseconds.

      use benchmark_timer
      
      real(r8) :: time
      
      call clock(time)
      write(*,*) 'The actual time is ', time, ' ms.'

Remarks

The system clock that is used can be modified. Three options are available at the moment: CPUTIME, DATETIME, SYSTEMTIME. They corresponds to the underlying functions cpu_time, date_and_time and system_clock, respectively.

Enumerations
enum	{ cputime = 0 , datetime = 1 , systemtime = 2 }
