Need correct with recurrence in google calendar api java

Question

Is it correct recurrence rule for icalendar?

RDATE;VALUE=PERIOD:19960403T020000Z/19960403T040000Z,19960404T010000Z/PT3H

When i set this string in event in google calendar via api i get event only with start from this.

Thats what i have:

       RDATE;TZID=America/New_York:19960403T020000Z

DateTime startDateTime = new DateTime("2020-12-16T09:00:00");
    EventDateTime start = new EventDateTime()
            .setDateTime(startDateTime)
            .setTimeZone("Europe/Minsk");
    event.setStart(start);

it's a java code where i create the main event:

Event event = new Event()
            .setSummary("Google I/O 2015")
            .setLocation("800 Howard St., San Francisco, CA 94103")
            .setDescription("A chance to hear more about Google's developer products.");
    DateTime endDateTime = new DateTime("2020-12-16T17:00:00");
    EventDateTime end = new EventDateTime()
            .setDateTime(endDateTime)
            .setTimeZone("Europe/Minsk");
    event.setEnd(end);
