F21 TC4 Xfce Print Settings display problem

[Robert Moskowitz]

When viewing completed jobs, the time shown (this is for an HP8600 if 
this matters) is Dec 1969.  No hours or minutes, just this date.

But going to http://localhost:631/admin to view the completed jobs 
report, the proper date is shown.

Only have Xfce installed, so can't check this out on other desktops.  
(seriously considering using Xfce over Gnome moving forward...)
