* $LynxId: parsdate.c,v 1.16 2013/01/05 02:00:30 tom Exp $
*
* This module is adapted and extended from tin, to use for LYmktime().
*
* Project : tin - a Usenet reader
* Module : parsedate.y
* Author : S. Bellovin, R. $alz, J. Berets, P. Eggert
* Created : 1990-08-01
* Updated : 2008-06-30 (by Thomas Dickey, for Lynx)
* Notes : This grammar has 8 shift/reduce conflicts.
*
* Originally written by Steven M. Bellovin <smb@research.att.com>
* while at the University of North Carolina at Chapel Hill.
* Later tweaked by a couple of people on Usenet. Completely
* overhauled by Rich $alz <rsalz@osf.org> and Jim Berets
* <jberets@bbn.com> in August, 1990.
*
* Further revised (removed obsolete constructs and cleaned up
* timezone names) in August, 1991, by Rich.
* Paul Eggert <eggert@twinsun.com> helped in September 1992.
* Roland Rosenfeld added MET DST code in April 1994.
*
* Revision : 1.13
* Copyright : This code is in the public domain and has no copyright.
