hideCalendar function causing incorrect display of date values

When editing an existing online contribution, we assign hideCalendar to true for the receive_date field in order to freeze the date value and suppress the calendar widget. This is the right behavior. However, when hideCalendar is assigned the 'frozen' date displayed is incorrect.

Example:
Online transaction with receive_date value in contribution record = '2010-03-25 15:56:33'
When displayed on contribution edit page - output is: "May 20th, 3" (should be "March 25, 2010")
