No.  For March 12 I get what I expect - EDT.

Yes, that is exactly what I get and that seems right to me.
I was just questioning the one first posted above that was:
  date -r 1173679260            resulting in:
  Mon Mar 12 02:01:00 EST 2007
That would be the EDT figures, except it is labeled EST
But, if it was really EST (and thus need the zonefile updated)
I thought it would say:
  Mon Mar 12 01:01:00 EST 2007

OK.   So the earlier post must have been a typo.
