The MongoDate class

(PECL mongo >=0.8.1)


This extension that defines this class is deprecated. Instead, the MongoDB extension should be used. Alternatives to this class include:


Represent date objects for the database. This class should be used to save dates to the database and to query for dates. For example:

Example #1 Storing dates with MongoDate


// 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)));


MongoDB stores dates as milliseconds past the epoch. This means that dates do not contain timezone information. Timezones must be stored in a separate field if needed. Second, this means that any precision beyond milliseconds will be lost when the document is sent to/from the database.
