I'm attempting to use date->parse to test a user's entry in a form's date field, but I'm getting unexpected results.

With:
local('date_start' = date('2012-04-30'))

The following:
#date_start->parse('0000-00-00', -format='%Q')
#date_start

Outputs:
true
0002-11-30

While this:
#date_start->asCopy->parse('0000-00-00', -format='%Q')
#date_start

Outputs:
true
2012-04-30

*This is the result I need.*

But then if the user enters the date in the wrong format, for example:
local('date_start' = date('04-30-2012'))
or omits the day:
local('date_start' = date('2012-04'))

The same code:
#date_start->asCopy->parse('0000-00-00', -format='%Q')

....outputs true, when I'm expecting false.

The docs say, "Returns True if the string parameter is in the proper date format or otherwise False." - but shouldn't it say, "...if the Date Object is in the proper date format..."?

Because if I do this, which is not -format='%Q':
#date_start->asCopy->parse('00-00-0000', -format='%Q')
....the result is still 'true'.

So somewhere I'm going astray - but where?
