[Zope] date in Z Gadfly Database

[Angietel]

When i create a table, one of the fields is consider as date type, but the Z Gadfly Database does not allow me to do that, it only accepts INTEGER instead of DATE type.   The following is my SQL for creating a table:-   CREATE TABLE customer (custid VARCHAR(10), custname VARCHAR(15), custactdate DATE, custadd1 VARCHAR(30), custadd2 VARCHAR(30))   Please let me know if i got an error.Thank You.
