Test Fixtures - Oracle date

What is the proper way of setting a test fixture for a date field in
Oracle db? I’ve tried various
ways like switching the year and no luck.

My test fixture is:

first:
id: 1
department_id: 1
last_name: test1
first_name: first1
birth_date: 2004-01-26 00:00:00
country_of_origin: Canada
job_title: Programmer
created_on: 2004-01-26 00:00:00
created_by: testuser
updated_on: testuser
created_on: 2004-01-26 00:00:00
user_id: testuser

I keep on getting ActiveRecord::StatementInvalid: OCIError: ORA-01841:
(full) year must be between -4713 and +9999, and not be 0…

This should work:

created_on: <%= Time.now.to_s(:db) %>

Thanks Nicholas. The reason why it didnt work for me was because a
typo. I have 2 created_on fields which conflicted.
