Description of problem:
In the Preferences page, there is a setting for "Timezone used to display dates and times".  If I set a value for this, most times are displayed correctly in my selected timezone, but the Last Closed field is not.

Version-Release number of selected component (if applicable):
4.4.0009

How reproducible:
Always

Steps to Reproduce:
1. Go to https://bugzilla.redhat.com/userprefs.cgi
2. Change the "Timezone used to display dates and times" field to "Australia/Brisbane"
3. Go to https://bugzilla.redhat.com/show_bug.cgi?id=950315

Actual results:
Reported and Modified dates are correctly shown with EST timezone, but Last Closed is shown with no timezone (and thus differs from Modified by 14 hours).

Expected results:
all dates and times should be shown adjusted for the user's selected timezone.

Additional info:
none.
