Django Filter, date formatting parameters

django1.4

When the HTML page reads the Datetimefield field from the database, the displayed time format is inconsistent with the format stored in the database, for example, the database field content is 2012-08-26 16:00:00, but the page shows an. 4 p.m.,

In order for the page and the database to display consistent, need to be in the page format time, need to add <td>{{dayrecord.p_time|date: "y-m-d h:i:s"}}</td> a similar filter. Refresh the page to display normally.
