From 11ab0cd090bd9800da57ed390fd32e9d1623bb0f Mon Sep 17 00:00:00 2001
From: Chris Hanson <org/chris-hanson/cph>
Date: Wed, 24 Apr 1996 03:21:30 +0000
Subject: [PATCH] Implement support for time-zone information in decoded-time
 data type.  Generalize the procedure FILE-TIME->STRING so that it generates
 an RFC-822 time string (when time-zone information is available from the
 microcode).
