如果我做对了，请考虑：

class Modelname(models.Model):
    """(Modelname description)"""

    confirmation_timestamp = models.DateTimeField(blank=True)

    def _set_confirmation(self, value):
        if not value:
            self.confirmation_timestamp = None
        else:
            self.confirmation_timestamp = datetime.datetime.now()

    def _get_confirmation(self):
        return bool(self.confirmation_timestamp)

    confirmation = property(_get_confirmation, _set_confirmation)
    confirmation.short_description = "Confirmation"
    confirmation.boolean = True # have it nicely displayed in admin
