This menu is useful if you run a membership site in which your users are allowed to set their local timezone value.

The first parameter lets you set the “selected” state of the menu. For example, to set Pacific time as the default you will do this:

echo timezone_menu('UM8');

Please see the timezone reference below to see the values of this menu.

The second parameter lets you set a CSS class name for the menu.

The fourth parameter lets you set one or more attributes on the generated select tag.
