{
RecurrenceRule RecRule = (RecurrenceRule)new MonthlyRecurrenceRule(0, new RecurrenceRange());

.... Some code to get frequency, interval, etc. from database

RecRule = AddExceptionstoRule(RecRule, myCal.id);
string RRule = RecRule.ToString();
//Everything is correct except for the EXDATE string which has hours/days that are off by an hour/day
}

private RecurrenceRule AddExceptionstoRule(RecurrenceRule RecRule, long CalendarID)
    {
        List<fnbl_pim_calendar_exception> CalendarExceptionCollection = GetCalendarExceptionCollection(CalendarID);
        foreach (fnbl_pim_calendar_exception myCalEx in CalendarExceptionCollection)
            RecRule.Exceptions.Add(myCalEx.occurrence_date);
        return RecRule;
//values in collection are
//2/21/2009
//2/24/2009
//3/7/2009
//3/13/2009
//3/20/2009
//3/27/2009
}

Hello Albert,

Thank you for sending us the sample code. The problem seems to be that the exception dates are being supplied in Local time. The recurrence-related classes require that dates are UTC. Specifying the type should solve the problem:

DateTime.SpecifyKind(myCalEx.occurrence_date, DateTimeKind.Utc);

We'll consider making this requirement optional and/or state this more clearly in the documentation. I'm sorry for the inconvenience.

Sincerely yours,
