I would like to use getDate() to the date of Zend_Date Object without the time part.

1)
I set the default timezone as Asia/Hong_Kong (GMT +8)

2)
print out the Zend_Date::now()->get()
result: 1194583304 (2007-11-09T12:41:44+08:00)

3)
print out the Zend_Date::now()->getDate()->get()
result: 1194566400 (2007-11-09T08:00:00+08:00)

But I expect the result of 3) should be (2007-11-09T00:00:00+08:00)

How can I solve this problem ?
