function timeago_time_zones in Timeago 7.2

Generate an array of time zones and their local time & date.

This function is identical to system_time_zones() except that it allows specifying a custom date format for the local time and date. This difference allows using formats other than the default Long date format, which is important when a Timeago format is the default since that would include hard-to-read escaped HTML markup.

Parameters

$blank: (Optional) If evaluates true, prepend an empty time zone option to the array.

$date_format: (Optional) The format of the human-readable date values.

Return value

An associative array of time zones. Keys are zone IDs and values are the current local datetime + UTC offset.

Code

function timeago_time_zones($blank = NULL, $date_format = '') {
  $zonelist = timezone_identifiers_list();
  $zones = $blank ? array(
    '' => t('- None selected -'),
  ) : array();
  foreach ($zonelist as $zone) {

    // Because many time zones exist in PHP only for backward compatibility
    // reasons and should not be used, the list is filtered by a regular
    // expression.
    if (preg_match('!^((Africa|America|Antarctica|Arctic|Asia|Atlantic|Australia|Europe|Indian|Pacific)/|UTC$)!', $zone)) {
      $zones[$zone] = t('@zone: @date', array(
        '@zone' => t(str_replace('_', ' ', $zone)),
        '@date' => format_date(REQUEST_TIME, 'custom', $date_format . ' O', $zone),
      ));
    }
  }

  // Sort the translated time zones alphabetically.
  asort($zones);
  return $zones;
