Examples with DateTime net.fortuna.ical4j.model.DateTime used on opensource projects

Example 46 with DateTime

use of net.fortuna.ical4j.model.DateTime in project zm-mailbox by Zimbra.

the class SchedulingViewOfTnef method getDueDate.

/**
 * @return the time in UTC that the meeting object was sent or null
 * @throws IOException
 */

        return null;
    }

    return timeVal;
}

Example 47 with DateTime

use of net.fortuna.ical4j.model.DateTime in project zm-mailbox by Zimbra.

the class MapiPropertyId method getDateTimeAsUTC.

/**
 * PT_SYSTIME properties wrap FILETIME which is a count of seconds since start of 1601
 * Note that some PT_SYSTIME properties are actually stored such that if they are treated
 * as UTC times, the day/month/year/hour/min etc components are correct in localtime.
 * Calling this method for such properties will result in a DateTime which doesn't reflect
 * the underlying real date and time on its own - but this can still be useful.
 * @param schedView
 * @return DateTime object equivalent to a PT_SYSTIME property where that property
 *         represents a time in UTC
 * @throws IOException
 */

    }
    DateTime icalDateTime = new net.fortuna.ical4j.model.DateTime(javaDate);

}

Example 48 with DateTime

use of net.fortuna.ical4j.model.DateTime in project zm-mailbox by Zimbra.

the class TZRule method getDtStart.

/**
 *   From initial TNEF to iCalendar Spec.
 *       The DTSTART property can be hard-coded to 16010101T000000. This is a value that
 *       works well across many calendar client apps.
 *   Note: Some examples seen are similar to this but include the hour of the transition.
 *         Suspect that is useful - so including it.
 *   Zimbra replaces our timezones with closest matchin known ones, so not worth trying
 *   to improve this to see if can choose an accurate start date/time in 1601.
 *
 * @param hr
 * @param min
 * @return

Example 49 with DateTime

use of net.fortuna.ical4j.model.DateTime in project zm-mailbox by Zimbra.

use of net.fortuna.ical4j.model.DateTime in project zm-mailbox by Zimbra.
