Fix Date Picker issue with Eastern Hemisphere users. 

Date Picker widget was returning an incorrect date when used in the eastern side of the dateline.   When selecting 9/30 from the calendar picker widget, it would return 9/29 to the date edit box.

This PR fixes the issue for the Eastern hemisphere, but needs to be tested for the U.S. / Western hemisphere to ensure it does not cause issues on that side of the world.
