Adrian,

As each row in the table already has both a date column and a time column I
don't know if I 'really' need a timestamp. When would a timestamp be really
needed?

Yes, I saw that on the doc page. This requires manually changing each row in
the table rather than using a date/time condition/function to to create the
single timestamp column. So, apparently there's not a way to modify the
table other than by hand.

Thanks,

Rich
