Storing dates with MongoDate
Represent date objects for the database. This class should be used to save dates to the database and to query for dates. For example:
<?php
// save a date to the database
$collection->save(array("ts" => new MongoDate()));
$start = new MongoDate(strtotime("2010-01-15 00:00:00"));
$end = new MongoDate(strtotime("2010-01-30 00:00:00"));
// find dates between 1/15/2010 and 1/30/2010
$collection->find(array("ts" => array('$gt' => $start, '$lte' => $end)));
?>
