problem using When in C#

I've taken this code straight from the sample and have noticed that
when I insert an event that includes a When then the event does not
show up in my calendar. However, if I leave the When of the event
emptry (null) then Google calendar defaults the event to the current
time and the event is displayed in the calendar. What am I doing wrong?

Sample code:

            When newTime = new When();
            newTime.StartTime = startTime;
            newTime.EndTime = endTime;
            newTime.AllDay = fAllDay;
            entry.Times.Add(newTime);
