"Unfortunately" because time stamps in DOS .ZIP archives
traditionally refer to _local_ times, not GMT.

A quick browse through the MS-DOS 7.1 kernel reveals a few
strings which appear to be names of environment variables.  TZ
doesn't seem to be among them.  Other versions of DOS will
differ, but MS-DOS 7.1 seems interested in:

   CONFIG=
   TMP= and TEMP=
   TEMPPROMPT= or perhaps \TEMPPROMPT=   (?)
   winbootdir=
   PATH=
   COMSPEC=

I'm guessing that some of these are simply set at boot time
for use by the default command shell, and never referenced
by DOS thereafter.
