My guess is that the environment setup 'su' does for the child process
includes something of the form

	TZ=$yourtz

without quotes around the variable!

All I can suggest is that you create some cute front end shell script like

	TZ='"'$TZ'"' exec /bin/su $*

and use that instead of 'su'.  It should fool the child's shell.
