17937	timeuntil doesn't work with datetime.date objects	dmitry.guyvoronsky@…	Aymeric Augustin	"It seems a bug exists in several django.utils.timezone methods, is_aware() and is_native(). This leads to error ""AttributeError: 'datetime.date' object has no attribute 'tzinfo'"" when timesince filter is applied to date object in Django template. Proof code

{{{
import time
from datetime import date
today = date.today()

from django.template import Context, Template
c = Context({""today"": today})
t = Template(""{{ today|timeuntil }}"")

print t.render(c)
}}}
