Fixed for Turba 4.2

I need this format in openldap to be able to sync with LDAPeople. It 
supports only '%Y%m%d'

Why are you changing the 'format_in' property?

After setting '%Y%m%d' format, kronolith does not longer show events 
like birthdays stored in the address book (turba), with  '%Y-%m-%d' it 
works.

/turba/config/attributes.local.php
<?php

$attributes['birthday'] = array(
     'label' => _("Birthday"),
     'type' => 'monthdayyear',
     'required' => false,
     'params' => array('start_year' => 1900, 'end_year' => null, 
'picker' => true, 'format_in' => '%Y%m%d', 'format_out' => 
$GLOBALS['prefs']->getValue('date_format')),
     'time_object_label' => _("Birthdays"),
);
$attributes['anniversary'] = array(
     'label' => _("Anniversary"),
     'type' => 'monthdayyear',
     'params' => array('start_year' => 1900, 'end_year' => null, 
'picker' => true, 'format_in' => '%Y%m%d', 'format_out' => 
$GLOBALS['prefs']->getValue('date_format')),
     'required' => false,
     'time_object_label' => _("Anniversaries"),
);
