It seems that if the TZ environment is set (I tested America/Chicago and
GMT) the c/python/perl programs all work.  If unset, (even though
localtime exists, and corresponds to America/Chicago) all three
programs fail to call mtime.  

I think may have been setting TZ and confused the issue slightly when
testing the c and perl programs.  

Still, should TZ be set by the installer?  Where is the proper place
to set TZ in DragonflyBSD?  I certainly didn't unset it (intentionally
or otherwise.)
