Esteban,
I would come to this point :) CTOT is dangerous IMHO. Instead :

transform(ttoc(ltDateTime,1), '@R 9999/99/99 99:99:99')

or for a date :

transform(ttoc(dtot(ldDate),1), '@R 9999/99/99 99:99:99')

provide needed ODBC canonical format. It's free from any century, set date etc settings which might affect CTOT.
