 /**
- * Generates the timezone selection form and JavaScript.
+ * Generates a list of available timezone continents and cities.
  *
- * Note: 'UTC/UTC' is mapped to 'UTC' to form a valid option
+ * Two distinct array based on available timezones
+ * and the one selected in the settings:
+ *   - (0) continents:
+ *     + list of available continents
+ *     + special key 'selected' containing the value of the selected timezone's continent
+ *   - (1) cities:
+ *     + list of available cities associated with their continent
+ *     + special key 'selected' containing the value of the selected timezone's city (without the continent)
  *
- * Example: preselect Europe/Paris
- *  list($htmlform, $js) = generateTimeZoneForm('Europe/Paris');
+ * Example:
+ *   [
+ *     [
+ *       'America',
+ *       'Europe',
+ *       'selected' => 'Europe',
+ *     ],

+ *       ['continent' => 'Europe', 'city' => 'Paris'],
+ *       'selected' => 'Paris',
+ *     ],
+ *   ];
  *
+ * Notes:
+ *   - 'UTC/UTC' is mapped to 'UTC' to form a valid option
+ *   - a few timezone cities includes the country/state, such as Argentina/Buenos_Aires
+ *   - these arrays are designed to build timezone selects in template files with any HTML structure
+ *
+ * @param array  $installedTimeZones  List of installed timezones as string
  * @param string $preselectedTimezone preselected timezone (optional)
  *
- * @return array containing the generated HTML form and Javascript code
