Let another variable change the value passed to Windows environment:
$ printenv TZ
Europe/Berlin
$ cmd /c echo %TZ%
Europe/Berlin
$ export CYGWIN_WINENV_TZ=CET-1CEST
$ printenv TZ
Europe/Berlin
$ cmd /c echo %TZ%
CET-1CEST
$ export CYGWIN_WINENV_TZ=
$ cmd /c echo %TZ%
%TZ% (which means TZ is not set)
