Just to inform everyone: I have made a slight change on the my post earlier concerning the integration of Profile Birthdays and Calendar 6.2. It appeared that for users with a time offset other than 0 the modification was moving the user's birthdays as many months forward or backward as the time offset.
Please refer to the previous post concerning this modification. The changes are a new variable declaration ignoring the time offset and the use of that variable in the database query.
