+NLS_Date_Format
+Allows you to use a date format other than the Oracle Lite default. When a literal
+character string appears where a date value is expected, the Oracle Lite database
+tests the string to see if it matches the formats of Oracle, SQL-92, or the value
+specified for this parameter in the POLITE.INI file. Setting this parameter also
+defines the default format used in the TO_CHAR or TO_DATE functions when no
+other format string is supplied.
+
+For Oracle the default is dd-mon-yy or dd-mon-yyyy, and for SQL-92 the default is
+yy-mm-dd or yyyy-mm-dd.
+
+Using 'RR' in the format forces two-digit years less than or equal to 49 to be
+interpreted as years in the 21st century (2000-2049), and years over 50 as years in
+the 20th century (1950-1999). Setting the RR format as the default for all two-digit
+year entries allows you to become year-2000 compliant. For example:
+NLS_DATE_FORMAT='RR-MM-DD'
+
+You can also modify the date format using the ALTER SESSION command.
