In the Django admin site, how do I change the display format of time fields?

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”.
