For showing a human readable MongoDate, you can use something like this:
<?php
date('Y-M-d h:i:s', $yourDate->sec);
?>
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:
소개
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);
?>

How do the two Mongo drivers determine if they can translate something into the ISODate format?
Does mongo.so require a class type of MongoDate, or does it determine by data returned by __toString() (i.e., "0.12345678 1234567890")?
Does mongodb.so require a class type of \MongoDB\BSON\UTCDateTime, or does it determine by data returned by __toString() (i.e., "1234567890123")?

>> the ISODate format?
For the record, ISODate is just a helper function in the mongo shell. The actual BSON type is 0x09 in the BSON spec and is best referred to as "UTC date time".

>> Does mongodb.so require a class type of \MongoDB\BSON\UTCDateTime, or does it determine by data returned by __toString() (i.e., "1234567890123")?
The driver requires a MongoDB\BSON\UTCDateTime object in order to encode a BSON date type. The relevant instanceof check during BSON encoding is here if you care to see it. The __toString() function exists purely as a convenience for userland applications. The driver does not use it outside of tests.

The legacy mongo.so driver is similar in that it requires a MongoDate object in order to encode a BSON date type (relevant code is here).

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);
?>
