You have something to look forward to.

Not only do the DATE and TIME commands supplied with the 32-bit CMD command
interpreter display the current timezone and support the /N switch (which
IBM's documentation describes, you will find, but which the 16-bit CMD does
not actually implement), but they *also* operate correctly when it comes to
timezone support and the TZ environment variable.  So, too, incidentally, do
the various date and time sequences in the PROMPT environment variable.
