DST on very old FreeBSD system

[Brett Glass]

John:

/etc/localtime on the 2.2.8 system begins with a series of nulls, 
not the string "TZif". However, some of our other clients have
4.x systems whose /etc/localtime files do begin with "TZif".
If you could send or post the files for the MST7MDT zone in both
formats, it'd be a great help.

It'd be nice if administrators could just download the relevant 
files and drop them into /etc/localtime. Perhaps someone with the 
power to do so could upload the zones in both formats to directories
on ftp.freebsd.org, so folks could bring in the zone(s) they needed 
via the "fetch" program.
