Example 1 with TZRule

use of com.zimbra.cs.util.tnef.mapi.TZRule in project zm-mailbox by Zimbra.

the class SchedulingViewOfTnef method initTZinfo.

/**
     * Initialise timezone related fields.
     * Replies from Outlook 2007 related to a recurrence or an instance
     * of a recurrence had :
     *     PidLidTimeZoneDescription,PidLidTimeZoneStruct,
     *     PidLidAppointmentTimeZoneDefinitionStartDisplay and
     *     PidLidAppointmentTimeZoneDefinitionEndDisplay present but NOT
     *     PidLidAppointmentTimeZoneDefinitionRecur
     * further, the StartDisplay/EndDisplay properties were appropriate to the
     * Outlook client replying and were NOT related to the originally sent ICAL.
     *
     * The Outlook originated TimeZone names associated with
     * StartDisplay/EndDisplay/Recur props seem "nicer" than the names
     * used in PidLidTimeZoneDescription - so, tend to prefer those.
     *
     * @throws IOException
