Second Intrinsic (subroutine)

     CALL Second(Seconds)

Seconds: REAL; scalar; INTENT(OUT).

Intrinsic groups: unix.


Returns the process's runtime in seconds in Seconds--the same value as the UNIX function etime returns.

On some systems, the underlying timings are represented using types with sufficiently small limits that overflows (wraparounds) are possible, such as 32-bit types. Therefore, the values returned by this intrinsic might be, or become, negative, or numerically less than previous values, during a single run of the compiled program.

This routine is known from Cray Fortran. See CPU_Time Intrinsic, for a standard equivalent.
