doubleprecisionfunctiondsecndDSECND Using ETIME DSECND returns nothing

       DSECND Using the INTERNAL function ETIME.

       DSECND Using INTERNAL function CPU_TIME.

       DSECND Using ETIME_

       Purpose:

             DSECND returns the user time for a process in seconds.
             This version gets the time from the EXTERNAL system function ETIME.

       Purpose:

             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.
