From mboxrd@z Thu Jan 1 00:00:00 1970 From: J William Piggott Subject: [PATCH 2/3] tzset.3: There are only two TZ formats Date: Sun, 01 Feb 2015 08:16:26 -0500 Message-ID: <54CE272A.1090003@gmx.com> References: <54CE2689.7000704@gmx.com> Mime-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Return-path: In-Reply-To: <54CE2689.7000704-KK0ffGbhmjU@public.gmane.org> Sender: linux-man-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: Michael Kerrisk Cc: linux-man-u79uwXL29TY76Z2rM5mHXA@public.gmane.org List-Id: linux-man@vger.kernel.org tzset(3) currently states that there are three TZ formats. The first two it lists are actually variations of the POSIX-style TZ format, of which there are at least five variations. This patch corrects this to match the POSIX specification of TZ having only two formats. http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap08.html Signed-off-by: J William Piggott --- man3/tzset.3 | 21 ++++++--------------- 1 file changed, 6 insertions(+), 15 deletions(-) diff --git a/man3/tzset.3 b/man3/tzset.3 index ed7f406..8002ee5 100644 --- a/man3/tzset.3 +++ b/man3/tzset.3 @@ -90,12 +90,12 @@ below, Coordinated Universal Time (UTC) is used. .PP The value of .B TZ -can be one of three formats. -The first format is used -when there is no daylight saving time in the local timezone: +can be one of two formats. +The first format is a string of characters that directly represent the +timezone to be used: .sp .RS -.I std offset +.RI stdoffset[ dst [ offset ][, start [ /time ], end [ /time ]]] .RE .sp There are no spaces in the specification. @@ -110,15 +110,6 @@ east.
