The MongoDate class

(PECL mongo >=0.8.1)

Warning

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

简介

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

<?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)));

?>

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.

This extension is deprecated, but some people still have to use it.

Please, note that properties (sec, usec) are read-only.

You have to do something like this:

<?php

$d = new \MongoDate();

echo "\n" . $d->toDateTime()->format(\DateTime::ISO8601);

// move to future for 125 seconds
$d = new \MongoDate($d->sec + 125, $d->usec);

echo "\n" . $d->toDateTime()->format(\DateTime::ISO8601);

I wanted a way to check the age of a record.  This code will calculate the time between the creation date of the record, and return the seconds.  I use it for caching pages similar to the max-age header in a browser.  If the record is older, than my limit it deletes itself.

<?php
function microtime_diff( $start, $end=NULL ) {
        if( !$end ) {
            $end= microtime();
        }
        list($start_usec, $start_sec) = explode(" ", $start);
        list($end_usec, $end_sec) = explode(" ", $end);
        $diff_sec= intval($end_sec) - intval($start_sec);
        $diff_usec= floatval($end_usec) - floatval($start_usec);
        return floatval( $diff_sec ) + $diff_usec;
}

microtime_diff($cache['stamp']->sec);

For showing a human readable MongoDate, you can use something like this:

<?php
date('Y-M-d h:i:s', $yourDate->sec);
?>
