Date comparison

Hi,

XML Template header need to print  max date of  ship_date or c_confirm_date. Both are coming on the xml data file.

      <SHIP_DATE>21-AUG-20</SHIP_DATE>

      <C_CONFIRM_DATE>30-AUG-20</C_CONFIRM_DA

<?xdofx:greatest(xdofx:to_date(ship_date,'DD-MON-YY'),xdofx:to_date(c_confirm_date,'DD-MON-YY'))?>

However it's printing :  19-AUG-2020 08:56      --> Seems current date. No idea on time how it's deriving.

Does not seem to be doing the actual date comparisons.

Need to print:  30-AUG-20

Any input how to fix it.

thanks
