After the calling script receives the selected time zone, then it
determines what to do with it and how to reply to the user. So the
following tail dialog (after the confirmation) makes no sense:

You can make this change permanent for yourself by appending the line
        TZ='America/New_York'; export TZ
to the file '.profile' in your home directory; then log out and log in again.

Here is that TZ value again, this time on standard output so that you
can use the /usr/bin/tzselect command in shell scripts:
America/New_York

It needs to end after the user confirms, and the calling script takes
over from there. The tail dialog is distracting, confusing, and
unnecessary.
