- * Generates the timezone selection form and JavaScript.

+ * 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:
+ *   [

+ * 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
