On the Debian Wheezy distribution, since the last update of PHP5 to the version 5.4.35-0+deb7u2, the serialization of DateTime seems to be broken.
The problem occurs periodically and is reproducible with difficulties.

In my test environment, the problem occurs when I want to read data that are stored into the Redis Server.

During the authentication, when the problem occurs, the stack trace is :
[{"message":"Error: Invalid serialization data for DateTime object in \/var\/www\/XXXX\/front\/vendor\/symfony\/symfony\/src\/Symfony\/Component\/Security\/Core\/Authentication\/Token\/AbstractToken.php line 163","class":"Symfony\\Component\\Debug\\Exception\\FatalErrorException","trace":[{"namespace":"","short_class":"","class":"","type":"","function":"","file":"\/var\/www\/XXXX\/front\/vendor\/symfony\/symfony\/src\/Symfony\/Component\/Security\/Core\/Authentication\/Token\/AbstractToken.php","line":163,"args":[]}]}]

Another example during data retrieval from cache:
{"message":"Error: Invalid serialization data for DateTime object in \/var\/www\/XXXX\/front\/src\/XXXX\/APIBundle\/Service\/YYYYService.php line 144","class":"Symfony\\Component\\Debug\\Exception\\FatalErrorException","trace":[{"namespace":"","short_class":"","class":"","type":"","function":"","file":"\/var\/www\/XXXX\/front\/src\/XXXX\/APIBundle\/Service\/YYYYService.php","line":144,"args":[]}]}]

I've found a recent bug report in the EZPublish project that seems to be built on Symfony 2 components: Attached files to this issue are interesting because we have a valid and an invalid DateTime serialization.

Then I've downgraded my Debian Wheezy PHP5 package to this version : 5.4.4-14+deb7u14 , and the problem doesn't exists.

In mycase helped me.
I had to add the format to the serialize like so:
 public function serialize() {
        return \serialize(array(
              $this->myDateTimeObj->format('Y-m-d H:i:s'),

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

Can anyone reproduce this on a version of PHP still in active support?
