I'm not sure what FC4 has, but it may be old enough not to have the
upcoming 2007 USA changes.

For updating manually without RPM or yum...

If you have an FC6 system around, you can always just copy the zoneinfo
files.  The files are platform independent.  Grab everything under
/usr/share/zoneinfo from the new system and overlay it on top of the
old one.  If you only care about one particular time zone, say
"America/New_York", then you just need to copy that one file, e.g.
  /usr/share/zoneinfo/America/New_York

Or you can always grab the latest zoneinfo files from the original
upstream source and install them.   Homepage is

Basically run the commands...

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

You can also run the last "zic" command on the other continent definition
files as well if you want; or in one single command:

  zic -d /usr/share/zoneinfo -L leapseconds [abefnps]*

Also double check the file permissions when done.  Perhaps a:

  chown -R root:root /usr/share/zoneinfo
  chmod -R go-w /usr/share/zoneinfo/
