(PECL mongo >= 0.8.1)

MongoDate::__constructCreates a new date.

Description

public MongoDate::__construct ([ int $sec = time() [, int $usec = 0 ]] )

Creates a new date. If no parameters are given, the current time is used.

Parameters

sec

Number of seconds since January 1st, 1970.

usec

Microseconds. Please be aware though that MongoDB's resolution is milliseconds and not microseconds, which means this value will be truncated to millisecond resolution.

Return Values

Returns this new date.

Examples

Example #1 MongoDate::__construct() example

This example demonstrates creating a new date with the current time and a new date with a given time.

<?php

$d 
= new MongoDate();
echo 
"$d\n";
$d = new MongoDate(1234567890);
echo 
"$d\n";
$d = new MongoDate(strtotime("2009-05-01 00:00:01"));
echo 
"$d\n";

?>

The above example will output something similar to:

0.23660600 1235685067
0.00000000 1234567890
0.00000000 1241150401

Please note that the second parameter should be a microseconds value, not a miliseconds one, as stated in the documentation.

I am using the code below to show you what I mean:
<?php
    $example
= new \DateTime('2013-09-22T10:41:44.451999');
   
$seconds = $example->getTimestamp();

   
// this is what documentation misleads you to think is needed
   
$miliseconds = floor($example->format('u') / 1000);

   
// this is what you should really use
   
$microseconds = $example->format('u');
   
$fullToString = $example->format('Y-m-d\TH:i:s.uP');

   
$collection->insert(array(
       
'timeMicroseconds' => new \MongoDate($seconds, $microseconds),
       
'toString' => $fullToString,
    ));
   
$collection->insert(array(
       
'timeMiliseconds' => new \MongoDate($seconds, $miliseconds),
       
'toString' => $fullToString,
    ));
?>

Let's take a look in the database to see what is really stored:
{
    "_id" : ObjectId("523f07cfc2b581eb7f069b1d"),
    "timeMicroseconds" : ISODate("2013-09-22T07:41:44.451Z"),
    "toString" : "2013-09-22T10:41:44.451999+03:00"
}

{
    "_id" : ObjectId("523f07cfc2b581eb7f069b1e"),
    "timeMiliseconds" : ISODate("2013-09-22T07:41:44.000Z"),
    "toString" : "2013-09-22T10:41:44.451999+03:00"
}
