"AttributeError: 'module' object has no attribute 'day_abbr'" when using Admin to add instance of model with DateField, TimeField, or DateTimeField

[Lexo]

I'm running Django 1.2.1 on Python 2.5.4

Whenever I try to add a new instance of a model that contains one of either DateTimeField, DateField, or TimeField, I get "AttributeError: 'module' object has no attribute 'day_abbr'"

I have a feeling it's related to ​http://code.djangoproject.com/ticket/13560 but I'm not sure.

Here are my models. Adding a Baz works just fine, but adding a Bar causes the exception:

{{{from django.db import models

class Bar(models.Model):

name = models.TextField()
publish_date = models.DateTimeField()

class Baz(models.Model):

name = models.CharField(max_length = 10)
age = models.IntegerField()

}}}

And a traceback:
