Error with manage users

[krausyao]

I have a new install of Mantis 1.2.19 at http://digital-rails.com/mantis/manage_ ... w_page.php

When logged in as administrator and I click Manage, Manage Users the following error occurs:

APPLICATION ERROR #401

Database query failed. Error received from database was #1690: BIGINT UNSIGNED value is out of range in '(1466848118 - `krausyao_mantis_4`.`_user_table`.`date_created`)' for the query: SELECT *
FROM _user_table
WHERE ((1466848118 - date_created)<= 604800)
ORDER BY date_created DESC.

Please use the "Back" button in your web browser to return to the previous page. There you can correct whatever problems were identified in this error or select another action. You can also click an option from the menu bar to go directly to a new section.

PHP is set to version 5.6.22.
