CALL CPU_Time(Seconds)

`Seconds`: `REAL`

; scalar; INTENT(OUT).

Intrinsic groups: `f90`

.

Description:

Returns in `Seconds` the current value of the system time.
This implementation of the Fortran 95 intrinsic is just an alias for
`second`

See Second Intrinsic (subroutine).

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.
