django.contrib.admin.widgets.AdminDateWidget.Media.js missing core.js

[eddymul]

Steps To Reproduce:

from django.contrib import admin
w = admin.widgets.AdminDateWidget()
w.media.render_js()

Expected:
got js/core.js:

[u'<script type="text/javascript" src="/media/js/core.js"></script>',
 u'<script type="text/javascript" src="/media/js/calendar.js"></script>',
 u'<script type="text/javascript" src="/media/js/admin/DateTimeShortcuts.js"></script>']

Observed:
missing js/core.js:

[u'<script type="text/javascript" src="/media/js/calendar.js"></script>',
 u'<script type="text/javascript" src="/media/js/admin/DateTimeShortcuts.js"></script>']

Notes:
I tried

class MyForm(forms.Form):
  class Media:
    js = (settings.ADMIN_MEDIA_PREFIX + 'js/core.js',)

but it doesn't work because core.js is rendered last, but AdminDateWidget.media.js assumes that core.js has been evaluated.

add core.js to admin date/time widgets

core.js gets included by ModelAdmin._media() (see django/contrib/admin/options.py around line 253).
