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.
