earliest_date and latest_date may be functions; if so, they will be called each time before validating.

after_now means a time after the current timestamp; note that just a few milliseconds before now is invalid! today_or_after is more permissive, and ignores hours and minutes.

Examples:

>>> from datetime import datetime, timedelta
>>> d = DateValidator(earliest_date=datetime(2003, 1, 1))
>>> d.to_python(datetime(2004, 1, 1))
datetime.datetime(2004, 1, 1, 0, 0)
>>> d.to_python(datetime(2002, 1, 1))
Traceback (most recent call last):
    ...
Invalid: Date must be after Wednesday, 01 January 2003
>>> d.to_python(datetime(2003, 1, 1))
datetime.datetime(2003, 1, 1, 0, 0)
>>> d = DateValidator(after_now=True)
>>> now = datetime.now()
>>> d.to_python(now+timedelta(seconds=5)) == now+timedelta(seconds=5)
True
>>> d.to_python(now-timedelta(days=1))
Traceback (most recent call last):
    ...
Invalid: The date must be sometime in the future
>>> d.to_python(now+timedelta(days=1)) > now
True
>>> d = DateValidator(today_or_after=True)
>>> d.to_python(now) == now
True
