* caching.
*
* The objective is to provide a uniform interface to such data.
*
* The class name must be the same as the file name - i.e. the list name
* prefixed with 'extended_'.
*
* The variable name must be 'timezones_list', and is an array of possible
* values, each of which is a value => text pair.
*
* The text is displayed in a drop-down; the value is returned.
*
* If function timezones_value() exists, it is called to create the displayed
* text.
