It's stopped in systems running the Arthur Olson time zone code
(4.3-tahoe, SunOS 4.0 and later, and I think either current or future
versions of Mach, A/UX, Ultrix, and possibly others); the time zone file
"northamerica" says "last Sunday in October", and gives references
(October 26th and 27th editions of the Washington Post).

The file the person from HP cited is, I think, an HP-specific file;
systems with the Olson code have a bunch of files that specify the
rules, and should supply the "source" files from which those (binary)
files are generated (SunOS 4.x does, and I assume others do as well -
4.3-tahoe does, of course, since Berkeley only ships it in source form);
in SunOS, they're found in "/usr/share/lib/zoneinfo", as are the binary
files (either there or in subdirectories thereof).
