All of the following are contained in the locale setting of the operating system EXCEPT:

The currency symbol (e.g., '$', '€') is a specific formatting element defined within the locale settings (LC_MONETARY) to display monetary values correctly.

The language setting dictates the language used for messages, menus, and other text displayed by the operating system and applications, which is a core component of locale (LC_MESSAGES).

The timezone setting determines the local time and daylight saving rules, which is independent of linguistic or cultural preferences specified by the locale. Locale settings primarily influence how data is presented to the user based on geographical, political, or cultural regions, rather than chronological ones.

The thousands separator (e.g., ',', '.', ' ') is a numeric formatting convention specified by the locale (LC_NUMERIC) to improve readability of large numbers.
