For older systems I found:

http://articles.techrepublic.com.com/5100-10877_11-6163042.html?part=rss&tag
=feed&subj=tr

to be useful. Except the file name changed:

  # wget 'ftp://elsie.nci.nih.gov/pub/tzdata2007c.tar.gz'
  # tar -xzvf tzdata2007c.tar.gz
  # /usr/sbin/zic -d zoneinfo northamerica
  # cd zoneinfo
  # cp -r * /usr/share/zoneinfo/

  # # for eastern
  # /usr/sbin/zdump -v /usr/share/zoneinfo/EST5EDT | grep 2007
  # ln -fs /usr/share/zoneinfo/EST5EDT /etc/localtime

  # # for PST
  # /usr/sbin/zdump -v /usr/share/zoneinfo/PST8PDT | grep 2007
  # ln -fs /usr/share/zoneinfo/PST8PDT /etc/localtime

Excellent step-by-step.

I just updated my RedHat 8 webserver for my company with your steps.

I found many similar documents and sites and links and stuff, but I didn't
know which to trust.  My primary objective was to try to update my RedHat AS
2.1 server during a maintenance window while RedHat's up2date sites and
services were unavailable.

Thank you for this simple method.
