This module will make the date API available to other modules. Designed to provide a light but flexible assortment of functions and constants, with more functionality in additional files that are not loaded unless other modules specifically include them.

Code

function date_timezone_abbr($refresh = FALSE) {
  $cached = cache_get('date_timezone_abbreviations');
  $data = isset($cached->data) ? $cached->data : array();
  if (empty($data) || $refresh) {
    $data = array_keys(timezone_abbreviations_list());
    cache_set('date_timezone_abbreviations', $data);
  }
  return $data;
}
