Thanks.  So, since everybody agrees, I committed as revision 106162
the changes to nt/config.nt that make current-time-zone and the
strftime's %Z format return a non-empty string on MS-Windows.

emacs -Q
M-: (format-time-string "%Z) ==> ""
M-: (format-time-string "%z) ==> "-0700"
 
The %Z string is incorrect. In my case, it should be (as it is in
Emacs 20 and Emacs 22.1): "Pacific Daylight Time".
 
This same bug appears in Emacs 23.  This is a regression from Emacs
22.1.

In GNU Emacs 22.2.1 (i386-mingw-nt5.1.2600)
 of 2008-03-26 on RELEASE
Windowing system distributor `Microsoft Corp.', version 5.1.2600
