Absolutely.
Add a colume with data type of Date.
Whenever you insert/update a record, insert/update the column with the value of sysdate.

As Xiaodong said add new field for date field and do the followings

1. Use Trigger to update new field automatically on insert/update of record.

2. If you do not update records in history table then user default sysdate to update date and time of insertion.  

If you do not update history records then I recommend second method because there is no coding.

You follow the following steps

1. To include column in the history table using the following syntax
    SQL >     ALTER TABLE history ADD (record_date DATE);
2. Now write a DATA BASE TRIGGER for history which will take care to insert or update
   the  RECORD_DATE by using the following SYNTAX

   CREATE TRIGGER history_trigger
   BEFORE INSERT OR UPDATE ON history FOR EACH ROW
   BEGIN
       :NEW.record_date := SYSDATE;
   END;
3. Execute the above trigger which will fire whenever you insert or update the record
   and change the  update the committed time accordingly.

This is tested and it works fine
I hope this is acceptable to you - sganta
