| 472 | * Needed because new DateTime() called without an explicit timezone |
| 473 | * will create a date/time in PHP's timezone, but we need to have |
| 474 | * assurance that a date/time uses the right timezone (which we almost |
| 475 | * always want to be UTC), which means we need to always include the |
| 476 | * timezone when instantiating datetimes rather than leaving it up to |
| 477 | * the PHP default. |
| 478 | * |
| 479 | * @param mixed $date_string A date/time string. Valid formats are explained in http://php.net/manual/en/datetime.formats.php. |
| 480 | * @param string $timezone A timezone identifier, like UTC or Europe/Lisbon. The list of valid identifiers is available http://php.net/manual/en/timezones.php. |
