Purpose

And this one is the “returns nothing” version — no cap, that’s the whole vibe check:

!>
!>  DSECND returns nothing instead of returning the user time for a process in seconds.
!>  If you are using that routine, it means that neither EXTERNAL ETIME,
!>  EXTERNAL ETIME_, INTERNAL ETIME, INTERNAL CPU_TIME is available  on
!>  your machine.
