## 9.3.33 CPU_TIME (TIME)

Description: | Returns a processor-dependent approximation of the processor time in seconds. This is a new intrinsic procedure in Fortran 95.
Class: | Subroutine
Arguments: | TIME must be scalar and of type real. It is an INTENT(OUT) argument. If a meaningful time cannot be returned, a processor-dependent negative value is returned.

Examples

Consider the following:

       REAL time_begin, time_end
       ...
       CALL CPU_TIME(time_begin)
       ...
       CALL CPU_TIME(time_end)
       PRINT (*,*) 'Time of operation was ', time_end - time_begin, ' seconds'
