public function DateObject::setTimezone in Date 7

Same name and namespace in other branches

1. 7.3 date_api/date_api.module \DateObject::setTimezone()
2. 7.2 date_api/date_api.module \DateObject::setTimezone()

Overrides default DateTime function. Only changes output values if actually had time granularity. This should be used as a "converter" for output, to switch tzs.

In order to set a timezone for a datetime that doesn't have such granularity, merge() it with one that does.

Code

public function setTimezone($tz, $force = FALSE) {

  // PHP 5.2.6 has a fatal error when setting a date's timezone to itself.
  // http://bugs.php.net/bug.php?id=45038
  if (version_compare(PHP_VERSION, '5.2.7', '<') && $tz == $this
    ->getTimezone()) {

      ->getName());
  }
  if (!$this
    ->hasTime() || !$this
    ->hasGranularity('timezone') || $force) {

    // this has no time or timezone granularity, so timezone doesn't mean much
    // We set the timezone using the method, which will change the day/hour, but then we switch back
