From 2b15132f986df6e8dcc2355f6e3e618550d1922b Mon Sep 17 00:00:00 2001
From: Ulrich Drepper <drepper@redhat.com>
Date: Fri, 10 Aug 2001 02:09:02 +0000
Subject: Update.

	* locale/lc-time.c (_nl_parse_alt_digit): New function.
	* locale/localeinfo.h: Add prototype for it.
	* time/strptime.c (get_alt_number): Use _nl_parse_alt_digit to get
	the value.  Correct computation of hour for %OI.  If no %EC given
	but %Ey use numeric formular.
