|
<p>This is a summary of the information about the change in Daylight
|
|
Savings Time rules and how the change affects FreeBSD releases.</p>
|
|
|
|
<p>In 2005 several countries, including the United States of America
|
|
and Canada, passed legislation changing when Daylight Savings Time
|
|
begins and ends. That change takes effect in 2007. For the time
|
|
zones affected by the change Daylight Savings Time will begin on
|
|
March 11th (instead of April 1st) and end on November 4th (instead
|
|
of October 28th).</p>
|
|
|
|
<p>FreeBSD uses <tt>/etc/localtime</tt> to control the conversion of
|
|
the system's internal representation of time (based on UTC) to the
|
|
format appropriate for the local time zone. That file gets
|
|
copied from one of the files in <tt>/usr/share/zoneinfo</tt> by the
|
|
tzsetup(8) command, usually as part of the initial installation
|
|
procedure. The change in Daylight Savings Time rules affects the
|
|
files in <tt>/usr/share/zoneinfo</tt> for the time zones affected by
|
|
the legislation passed in 2005.</p>
|
|
|
|
<p>Of the release branches supported by the FreeBSD Security Team
|
|
as of February 2007, FreeBSD-6.2 and FreeBSD-5.5 have up to date
|
|
zoneinfo files. FreeBSD-6.1 has correct zoneinfo files for
|
|
time zones in the United States of America but out of date
|
|
zoneinfo files for some of the other countries affected (for
|
|
example Canada). An Errata Notice will be released shortly
|
|
to update the zoneinfo files in FreeBSD-6.1.</p>
|
|
|
|
<p>For the development branches HEAD, RELENG_6, RELENG_5, and
|
|
RELENG_4 all have the correct zoneinfo files in them.</p>
|
|
|
|
<p>NOTE: <tt>/etc/localtime</tt> currently does not get updated when
|
|
the cvsup/buildworld/etc system update procedures are used. If a machine
|
|
was installed using one of the releases not listed above it will
|
|
probably have an outdated <tt>/etc/localtime</tt> file. That file can
|
|
be updated by running tzsetup(8).</p>
|
|
|
|
<p>For older systems no longer under support the misc/zoneinfo
|
|
port can be installed to update the <tt>/usr/share/zoneinfo</tt> files,
|
|
followed by running tzsetup(8) to update <tt>/etc/localtime</tt>.</p>
