NAME

       tai64nlocal - converts precise TAI64N timestamps to a human-readable format.

SYNOPSIS

       tai64nlocal

DESCRIPTION

       tai64nlocal  reads lines from stdin. If a line does not begin with @, tai64nlocal writes it to stdout without change. If a line begins with
       @, tai64nlocal looks for a timestamp after the @, in the format printed by tai64n(8), and writes the line to stdout with the timestamp con-
       verted to local time in ISO format: YYYY-MM-DD HH:MM:SS.SSSSSSSSS.

       For example, in the US/Pacific time zone, the input line

	 @4000000037c219bf2ef02e94 mark

       should be printed as

	 1999-08-23 21:03:43.787492500 mark

       Beware,	however,  that the current implementation of tai64nlocal relies on the UNIX localtime library routine to find the local time. Some
       localtime implementations use a broken time scale that does not account for leap seconds. On systems that use the Olson tz library (with an
       up-to-date leap-second table), you can fix this problem by setting your time zone to, e.g, right/US/Pacific instead of US/Pacific.

       Beware also that most localtime implementations are not Y2038-compliant.

       tai64nlocal does not allocate any memory after it starts, except possibly inside localtime.

EXIT CODES

       tai64nlocal exits 0 when it sees end of input. It exits 111 without an error message if it has trouble reading stdin or writing stdout.

NAME

       DateTime::TimeZone::Local::Unix - Determine the local system's time zone on Unix

VERSION

       version 1.63

SYNOPSIS

	 my $tz = DateTime::TimeZone->new( name => 'local' );

	 my $tz = DateTime::TimeZone::Local->TimeZone();

DESCRIPTION

       This module provides methods for determining the local time zone on a Unix platform.

HOW THE TIME ZONE IS DETERMINED

       This class tries the following methods of determining the local time zone:

       o   $ENV{TZ}

	   It checks $ENV{TZ} for a valid time zone name.

       o   /etc/localtime

	   If this file is a symlink to an Olson database time zone file (usually in /usr/share/zoneinfo) then it uses the target file's path name
	   to determine the time zone name. For example, if the path is /usr/share/zoneinfo/America/Chicago, the time zone is "America/Chicago".

	   Some systems just copy the relevant file to /etc/localtime instead of making a symlink.  In this case, we look in /usr/share/zoneinfo
	   for a file that has the same size and content as /etc/localtime to determine the local time zone.

       o   /etc/timezone

	   If this file exists, it is read and its contents are used as a time zone name.

       o   /etc/TIMEZONE

	   If this file exists, it is opened and we look for a line starting like "TZ = ...". If this is found, it should indicate a time zone
	   name.

       o   /etc/sysconfig/clock

	   If this file exists, it is opened and we look for a line starting like "TIMEZONE = ..." or "ZONE = ...". If this is found, it should
	   indicate a time zone name.

       o   /etc/default/init

	   If this file exists, it is opened and we look for a line starting like "TZ=...". If this is found, it should indicate a time zone name.
