Использование даты в проверочном ограничении, Oracle

Я пытаюсь проверить добавление следующего ограничения, но Oracle возвращает ошибку, показанную ниже.

ALTER TABLE Table1
ADD (CONSTRAINT GT_Table1_CloseDate
CHECK (CloseDate > SYSDATE),
CONSTRAINT LT_Table1_CloseDate
CHECK (CloseDate <= SYSDATE + 365)),
CONSTRAINT GT_Table1_StartDate
CHECK (StartDate > (CloseDate + (SYSDATE + 730))));

Ошибка:

Error report:
SQL Error: ORA-02436: date or system variable wrongly specified in CHECK constraint
02436. 00000 -  "date or system variable wrongly specified in CHECK constraint"
*Cause:    An attempt was made to use a date constant or system variable,
           such as USER, in a check constraint that was not completely
           specified in a CREATE TABLE or ALTER TABLE statement.  For
           example, a date was specified without the century.
*Action:   Completely specify the date constant or system variable.
           Setting the event 10149 allows constraints like "a1 > '10-MAY-96'",
           which a bug permitted to be created before version 8.
