Jquery to remove options in the date time picker hours field

Hello,

The date and time picker looks like this:

I want to use jquery to remove some of the hours in the hours field.  I've tried many things and none of them have worked.  This was my last attempt:

$("select[id$='Verbal_x0020_Agreem_5850c5df-4d63-4455-9dta-562890fe6ee1_$DateTimeFieldDateHours']").change(function() 
 {
 $("option[value='4 AM']").remove();
 });

Any ideas?

Thanks! Patti N.
