python - 'latest' django model is not latest? -

-

using django 1.6:

getting model db using latest returns model created date on instance returned lacks microseconds, means it's not latest, has same date stamp, microseconds included , therefore later (boolean comparison of datetime.datetime objects confirms it). what's going on?

mymodel(models.model):     <lots of fields>     created = models.datetimefield(auto_now_add=true)

and being retrieved with: latest = cls.objects.latest('created')

and:

latest.created datetime.datetime(2014, 11, 11, 17, 8, 43)

yet:

model_i_last_created.created datetime.datetime(2014, 11, 11, 17, 8, 43, 849155)

update: create 3 models using .create 1 returned latest or last first 1 created, not last.
