[TYPO3-english] problem with date2cal and date generation

[jochem nabuurs]

Hi list,

I'm having a problem with date2cal version 7.3.x and date generation in 
the backend. I'm using the dutch notation. When setting a date (f.e. for 
showing a CE in the future, and the day number is lower than the month 
number, the day and month are switched. So november 4th (04-11-2010) is 
shown as 11-04-2010 which corresponds to april 11th in dutch date 
notation. I've tried setting the date notation in TCA through the 
installmanager:

$TYPO3_CONF_VARS['SYS']['ddmmyy'] 		   = 'd-m-Y';
$TYPO3_CONF_VARS['SYS']['USdateFormat'] 	   = '';

And in the backend the label under the date field shows the following 
notation (which corresponds to the dutch notation): HH:MM dd-mm-yyyy

I've been looking for the answer for allmost 3 hours now, and can't seem 
to find the correct way to solve this. Version 7.2.0 seems to render the 
date correct but this version has some bugs when using powermail (date 
gets reset when submitting a powermail form, failing validation).

I hope someone can help me with this issue because the website on which 
this error occurs is allready live.

Thanks in advance.
