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

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).
