Description:
------------
I changed locale to Germany, created a datetime with microseconds, formatted the date, and the microseconds were zero.

This first appeared when SQL 2005 driver showed no microseconds for German users of my site.

The code is a simple test to show it's not caused by the SQL Server driver.

Reproduce code:
---------------
$robert = new DateTime('2009-02-04 15:55:25.321');
$robertf = $robert->format(CLocale::DateTimeFormatFull);
echo $robertf . "\r\n";

$robloc = setlocale(LC_ALL, 'German_Germany.1252');
echo $robloc . "\r\n";
$robert = new DateTime('2009-02-04 15:55:25.321');
$robertf = $robert->format(CLocale::DateTimeFormatFull);
echo $robertf . "\r\n";

$robloc = setlocale(LC_ALL, 'English_uk.1252');
echo $robloc . "\r\n";
$robert = new DateTime('2009-02-04 15:55:25.321');
$robertf = $robert->format(CLocale::DateTimeFormatFull);
echo $robertf . "\r\n";;

Expected result:
----------------
04/02/2009 15:55:25.321000
German_Germany.1252
04/02/2009 15:55:25.321000
English_United Kingdom.1252
04/02/2009 15:55:25.321000


Actual result:
--------------
04/02/2009 15:55:25.321000
German_Germany.1252
04/02/2009 15:55:25.000000
English_United Kingdom.1252
04/02/2009 15:55:25.321000
