Date validation not working correctly

Date validation not working correctly

Hi everybody

I'm new in jquery. In my MVC project most of the validations are done in jquery. All are working fine expect this date field. Let me describe my problem.

I have a date textbox, which is attached to datetimepicker. My code is below.

$("#DateTimeTextBox").datetimepicker({
            dateFormat: 'dd/mm/yy',
            timeFormat: 'hh:mm'
        });

For validating this field i'm using this code

'DateTimeTextBox': {
      required: true,
      date: true
    },

Here if we give the date format is 'mm/dd/yy'  for datetimepicker the validation is showing correct. if we give the date format like this 'dd/mm/yy', always show the validation error message "Please enter a valid date". But I'm giving the correct date like "25/11/2012". 

Is there anywhere need to set the date format for validation.

Thanks
