Time is not saving with Date

Question

I have a created a report and form. Now I am trying to populate one of the columns with a date and time. The column will store the date. However, it will not save the time. I am fairly certain that my process to set the field is correct as I am able to save the date/time in a string and the time stores correct.
The database column is of type Date.
The column is setup as follows:
Display As: Date Picker (YYYY-MM-DD HH24:MI)
Source Type: Database Column
Edit Mask: YYYY-MM-DD HH:MIPM
Any help would be appreciated.
Thanks,

Answer 1

OK. I was able to figure it out. I had to fully qualify the date format when making the assignment. i.e. TO_CHAR(v_today, 'YYYY-MM-DD HH24:MI').
Why is this?
Thanks,
Below is a subset of the code that I am using to assign the date field. My code is in the Process Point: On Submit - Before Computations and Validations
DECLARE
v_today estimate.row_updated%type;
BEGIN
select sysdate
into v_today
from dual;
-- Saves current date without time.
:P2_ROW_CREATED := v_today;
-- This works. Saves the date and the time.
:P2_ROW_UPDATED := TO_CHAR(v_today, 'YYYY-MM-DD HH24:MI');
END ;
