IE9 date picker is initialized with default date value

When no date is selected, the date picker has a default value of today's date. Calling picker.get('select') returns date info for today and the hidden input has a date value of today. Once picker.clear() is called, the date values are null as they should be. It would be ideal if the date picker did not start with default values so that it is not required to call picker.clear() any time a date picker is created to prevent issues with incorrect dates.
