Well, It depends. The Israeli time zone is not functioning properly in
M$ Windoze (they don't adjust to the yearly change in DST). I prefer my
Cygwin time to be correct even if the Windoze time is wrong.

The TZ env var (in it simplest form, as described by me) is fully
compatible with all UNIX system. The `zic' compiled file (localtime)
is compatible with Linux and some other UNICes (the file place and name
is VERY varied) but some systems (e.g. SGI IRIX) don't support it at
all (SGI has complex TZ format for this).

Note. The TZ is even used by some Windoze programs (I had a Netware NFS
      client that used it).
