Description:
------------
This is only relevant on the newer versions of mysql/mariaDB that support microsecond precision on timestamp columns.

minimum Mysql version: 5.6.4
minimum MariaDB version: 5.3

When the PDO attribute ATTR_EMULATE_PREPARES is false, any microseconds are dropped from timestamp columns.

I'm using:

MariaDB v10.0.10: mysql  Ver 15.1 Distrib 10.0.10-MariaDB, for debian-linux-gnu (x86_64) using readline 5.1

PHP 5.5.11-3+deb.sury.org~precise+1 (cli) (built: Apr 23 2014 12:23:08)
(also tested on PHP 5.5.9-1ubuntu4 (cli) (built: Apr  9 2014 17:11:57))

mysqlnd v5.0.11-dev

Test script:

Expected result:
----------------
PDO::ATTR_EMULATE_PREPARES = true:
2014-04-23 08:45:36.022588
PDO::ATTR_EMULATE_PREPARES = false:
2014-04-23 08:45:36.022588

Actual result:
--------------
PDO::ATTR_EMULATE_PREPARES = true:
2014-04-23 08:45:36.022588
PDO::ATTR_EMULATE_PREPARES = false:
2014-04-23 08:45:36
