With some help from Slurpee I have added another input field in the cpanel to enter a Time Zone Rule. This is then diplayed under the time zone name in Ultimate.cgi. I haven't added this code to the worldtime.cgi display.
I like this because I didn't want to change all the time zones serveral times. Although I must change all server offsets for my web site twice a year.
