how to convert date value(format) in Calendar(input controls)

Hi everyone

I am using webi 4.0

My problem is when i select calendar date(input Controls) i am able to display time stamp along with date in input Controls(MM/dd/yyyy 12:00:00 AM)

i want to change (MM/dd/yyyy 12:00:00 AM) to (yyyy-MM-dd ), when i select calendar date(input Controls)

where is the calendar date(input Controls)' format setting??

i dont want to show the time stamp in calendar date(input Controls) as my users dislike to see that timestamp .

Thanks & regards

'Before'

'After'  ( i want to change 'Before' to 'After')
