BTW, my original report (that the time zone was off by 4 hours) was 
misleading.  After comparing my results with those of Angelo Graziosi in 
Italy, I realized that, for both Angelo and me, emacs thought our local 
time zone was GMT minus one hour.  (This was in February, before 
daylight savings time.)

Thanks for looking into this.  I'm about to leave town for a few days, 
but maybe I'll make another attempt when I return (unless you've already 
solved it before then).
