SAS mentioned it has to do with the SPSS driver they use. Apparently it is not an easy fix so they forwarded the issue to second-line tech support.
The workaround you will need is split the dates in two columns. One with date and one with time.
data SPSS2;
set SPSS;
date = put(datepart(DatumSPSS), date9.);
time = put(timepart(DatumSPSS), time8.);
run;
Or you can tell the end user how to change the format of the date in SPSS.
