When loading the calendarAttribute page of the calendar test application (calendar.war attached) :
- by default, renderAsPopup = true when first loading the page, and it displays today's date in the date input entry (correct); when clicking in the date input entry, the calendar renders in a popup but the date changes to 2017, May or June, the exact date is not consistent.
- If unselecting the check box to change renderAsPopup = false, the inline calendar displays a date in the future (year 2017) instead of the current date.

The rendered date in the popup calendar was different when testing on different browsers, and it was not consistent when testing with the same browser; as example:
IE8: May 25, 2017
FF6: June 17, 2017
FF3.6: June 20, 2017

To reproduce the issue:
- deploy attached calendar.war file.
- navigate to the page: http://localhost:8080/calendar/calendarAttribute.jsf
- click in the date input entry where the current date is rendered.
