timezone

timezone(4)							   File Formats 						       timezone(4)

NAME

       timezone - default timezone data base

SYNOPSIS

       /etc/timezone

DESCRIPTION

       The  timezone  file contains information regarding the default timezone for each host in a domain. Alternatively, a single default line for
       the entire domain  may be specified. Each entry has the format:

	 Timezone-name	  official-host-or-domain-name

       Items are separated by any number of blanks and/or TAB characters. A `#' indicates the beginning of a comment; characters up to the end	of
       the  line  are not interpreted by routines which search the file. The timezone is a pathname relative to the directory /usr/share/lib/zone-
       info.

       This file is not actually referenced by any system software; it is merely used as a source file to construct the NIS  timezone.byname  map.
       This  map  is  read  by	sysidtool(1M)  to initialize the timezone of the client system at installation time. For more information, see the
       Solaris Express Installation Guide: Basic Installations.

       The timezone file does not set the timezone environment variable TZ. See TIMEZONE(4) for information to set the TZ environment variable.

EXAMPLES

       Example 1 Typical timezone line

       Here is a typical line from the /etc/timezone file:

	 US/Eastern	     East.Sun.COM #Sun East Coast

FILES

       /etc/timezone
