I'm confused.

Using /usr/sbin/tzselect to find TZ ends with the following (questions
have been deleted):

| You can make this change permanent for yourself by appending the line
|         TZ='Europe/Monaco'; 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/sbin/tzselect command in shell scripts:
| Europe/Monaco

So my question is whether one would really use CEST or the result of
tzseelct.  (Note:  I kept the OP's example of Monaco - I am really
in the U.S.)  And if it is something like CEST, what does one do in
the U.S., where some do not go on Daylight Savings (Summer) Time?
