# Internationalization and Localization

- [Coordinated Universal Time](/docs/server/reference/data-types/string-data-types/character-sets/internationalization-and-localization/coordinated-universal-time.md): Coordinated Universal Time (UTC) is the primary time standard by which the world regulates clocks and time, and is the internal storage format for MariaDB timestamp values.
- [Locales Plugin](/docs/server/reference/data-types/string-data-types/character-sets/internationalization-and-localization/locales-plugin.md): The LOCALES plugin enables the INFORMATION\_SCHEMA.LOCALES table and SHOW LOCALES statement, allowing users to view all locales compiled into the server.
- [Server Locale](/docs/server/reference/data-types/string-data-types/character-sets/internationalization-and-localization/server-locale.md): Server locale settings control the language for date and time functions via lc\_time\_names and the language for error messages via lc\_messages.
- [Setting the Language for Error Messages](/docs/server/reference/data-types/string-data-types/character-sets/internationalization-and-localization/setting-the-language-for-error-messages.md): Learn how to configure the lc\_messages and lc\_messages\_dir system variables to display server error messages in a supported local language.
- [Time Zones](/docs/server/reference/data-types/string-data-types/character-sets/internationalization-and-localization/time-zones.md): Complete Time Zones data type guide for MariaDB. Complete reference for syntax, valid values, storage requirements, and range limits for production use.
