The rules for determining the yearly start and end of daylight saving time in the United States have changed beginning in March of 2007. All the FreeBSD systems I am in charge of need new rules and I read an article that mentions FreeBSD and Linux and the /usr/share/zoneinfo data base which I found. In that directory are subdirectories for the continents and many binaries describing the rules for major cities or islands. /etc/localtime is a copy of whichever locality file in /usr/share/zoneinfo correctly mirrors one's local time. The problem, as I see it, is that we need a new America file. I ran across an article that referenced ftp://elsie.nci.nih.gov/pub/tzdata2006h.tar.gz Which turns out to be the source file for making all the location files. My question is, How do I get there from here? That file is obviously #included or otherwise used in something you make to generate the objects. Has this already been done somewhere for FreeBSD and will it work on systems ranging from FreeBSD4.7 up to 5.4? I use FreeBSD on our domain name and dhcp servers and want to get them ready well before this mini Y2K-like situation hits. Many thanks. For those who may be wondering, DST ends as it has for many years, on the last Sunday in October so the new rules don't take effect until March 11 of 2007.
