Examples

      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.

	Value related to the function cpu_time
enumerator	datetime = 1
	Value related to the function date_and_time
enumerator	systemtime = 2
	Value related to the function system_clock
