Add timezone to profile settings page

 - Users will have two options to select a timezone.
 - UTC and browser offset timezone are the two options for the application.
 - date-fns and date-fns-tz is used for date and time manipulations because:-
   - The package size of library is smaller.
   - It allows for importing functions to work with the native date object
     rather than having to create a moment instance that carries a larger payload.
