Contacts birthday one day later on Android device

[Axel]

Hi all,

I noticed that all contacts birthdays I add in roundcube appear to be 
one day later on my android phone.
When I add a new contact on my phone it gets synced to kolab correctly, 
but when I edit the contact in roundcube it's birthday is again wrong on 
my phone.

I use the latest kolab 3.0 release on centos 6.4 and ActiveSync for my 
Galaxy S3 (stock Samsung). System dates are ok and I found nothing 
unusual in my logs.

Has anyone else noticed this behaviour?

Regards, Axel
