F22 XFCE system-config-date not changing date/time system bar

[Robert Moskowitz]

In the past, this worked for me.  When I moved from the ET to elsewhere 
in the US or EU I would 'just' use system-config-date to change the 
timezone and within a minute I would see the new time reflected in the 
time widget.

But this past weekend in HongKong, it did not work.  Nor is it working 
now in Japan.  The system time is right:

$ date
Mon Nov  2 01:20:46 JST 2015

But the system bar is showing 11:20am

How do I fix this.  Other than trying a reboot or a logout...
