Those who can read and have not closed their mind have surmised by now that 
instead of saving the timezone *as provided by the user* in a cookie *as you 
proposed*, it could be saved in Local Storage or in a server-side session 
instead, whereas, with PHP at least, the session data could be held in a 
database.

Once you have looked deeper into those issues, you will have realized that 
*any* personal information is a matter of *privacy*.  Security is a 
different concept that you were the first to mention here, confusing the 
issue.

Iff they are aware of the issue and able to do something about it.  That’s 
the point.

It is fortunate that your vocabulary forms an empty intersection with mine.
