/**
* Returns a <select> tag populated with all the timezones in the world.
*
* The select_timezone_tag builds off the traditional select_tag function, and is conveniently populated with
* all the timezones in the world (sorted alphabetically). Each option in the list has a unique timezone identifier
* for its value and the timezone's locale as its display title. The timezone data is retrieved via the sfCultureInfo
* class, which stores a wide variety of i18n and i10n settings for various countries and cultures throughout the world.
* Here's an example of an <option> tag generated by the select_timezone_tag:
*
* <b>Options:</b>
* - display -
* identifer - Display the PHP timezone identifier (e.g. America/Denver)
* timezone - Display the full timezone name (e.g. Mountain Standard Time)
* timezone_abbr - Display the timezone abbreviation (e.g. MST)
* timzone_dst - Display the full timezone name with daylight savings time (e.g. Mountain Daylight Time)
* timezone_dst_abbr - Display the timezone abbreviation with daylight savings time (e.g. MDT)
* city - Display the city/region that relates to the timezone (e.g. Denver)
*
* <samp>
* <option value="America/Denver">America/Denver</option>
* </samp>
*
* <b>Examples:</b>
* <code>
* echo select_timezone_tag('timezone', 'America/Denver');
* </code>
*
* @param string field name
* @param string selected field value (timezone identifier)
* @param array additional HTML compliant <select> tag parameters
* @return string <select> tag populated with all the timezones in the world.
* @see select_tag, options_for_select, sfCultureInfo
