Menu
I recently added a new model to my site, and I'm using an admin.py file to specify exactly how I want it to appear in the admin site. It works great, but I can't figure out how to get one of my date fields to include seconds in it's display format. I'm only seeing values like "Aug. 27, 2011, 12:12 p.m." when what I want to be seeing is "Aug. 27, 2011, 12:12*:37* p.m."

Changing django admin default formats could be done changing the django locale formats for every type you want. Put the following on your admin.py file (or settings.py) to change datetime default format at your django admin. It will change the ModelAdmin's datetime formats on that file (or whole site if in settings).
To change the admin site header text, login page, and the HTML title tag of our bookstore's instead, add the following code in urls.py . The site_header changes the Django administration text which appears on the login page and the admin site. The site_title changes the text added to the <title> of every admin page.
Django provides a built-in admin module which can be used to perform CRUD operations on the models. It reads metadata from the model to provide a quick interface where the user can manage the content of the application. This is a built-in module and designed to perform admin related tasks to the user.
Try this in the ModelAdmin:
def time_seconds(self, obj): return obj.timefield.strftime("%d %b %Y %H:%M:%S") time_seconds.admin_order_field = 'timefield' time_seconds.short_description = 'Precise Time' list_display = ('id', 'time_seconds', ) Replacing "timefield" with the appropriate field in your model, of course, and adding any other needed fields in "list_display".

digging around I ended here but applied a different approach to my app.
Changing django admin default formats could be done changing the django locale formats for every type you want.
Put the following on your admin.py file (or settings.py) to change datetime default format at your django admin.
from django.conf.locale.es import formats as es_formats es_formats.DATETIME_FORMAT = "d M Y H:i:s" It will change the ModelAdmin's datetime formats on that file (or whole site if in settings).
It does not breaks admin datetime filters and order features as @Alan Illing has point out in comments .
hope this help in future
