For just the USA changes to DST for 2007 you only need tzdata 2005l (L)
or later (upstream data was published Aug 22, 2005).  Of course you're
always best to get the latest version as there have been many other
timezone changes besides just the DST one.

The current version right now is 2007a (published just yesterday!)
Prior to this week the most recent version was 2006p.


If necessary for older unsupported systems where a yum or rpm
update are not possible, you can always:

  1. Copy the zoneinfo "binary" files from a newer system (files
       under /usr/share/zoneinfo), or

  2. Recompile the timezone files manually.  Download the tz tar
      file from http://www.twinsun.com/tz/tz-link.htm and run the
      zic(1) command on them.   e.g., something like:

mkdir /tmp/tzdata
cd /tmp/tzdata
wget ftp://elsie.nci.nih.gov/pub/tzdata2006p.tar.gz
tar -xzf tzdata2006p.tar.gz
cp *.tab /usr/share/zoneinfo/
zic -d /use/share/zoneinfo -L leapseconds northamerica

You can also run zic on the other "continents" as you care
about.  Hawaii for instance may want to compile "pacific".
