Details:

The following:

DATA LIST notable LIST /when (DATETIME17).
begin data.
"19-01-2019 20:00"
"19-01-2019 21:00"
end data.

DESCRIPTIVES
    /VARIABLES = when
    /STATISTICS = MEAN,STDDEV,RANGE,MIN,MAX.

produces a result similar to:

     │N│  Mean  │Std Dev│ Range │Minimum          │Maximum        
 
 when│2│1.4E+010│2545.58│3600.00│19-JAN-2019 20:00│19-JAN-2019
21:00


The formats for N, Minimum and Maximum are reasonable, but those for
Mean,Std Dev and Range are not meaningful.
Mean should assume the same format as the variable, and (in this case)
Range and Std Dev should be of TIME (not DATETIME) format.

In general a more intellegent method of assigning formats in the output
needs to be worked out.
