Zoho Sync for iPhone and iPod - timezone

Hi,
Actually the msync.zoho.com function with my Iphone works fine for calendars and contacts. BUT if I put in a new appointment in the Iphone calendar and sync it, the date is set 9 hours later in Zoho. I am quite sure both time zones are set to MET (Berlin).
That sync function is very important to me and I was quite happy to have it working...but that time difference makes it unreliable at the moment.
Did I do something wrong / will you fix it?

Thanks
