TimeUtil.serialize_time doesn't support Occurrences

[bennettaur]

Maybe this is more of a feature request, but I'm looping through occurrences and based on a set of criteria, I want to add that occurrence as an exception time. Everything allows me to, but when I go to serialize the schedule it fails with ArgumentError: cannot serialize "2017-10-15T00:00:00.000Z", expected a Time. This is easily overcome if I use .to_time or .start_time but it seems natural for occurrences to be supported

example code:

schedule.next_occurrences(10).map do |occurrence|
    if add_exception?(occurrence)
        schedule.add_exception_time(occurrence)
    end
end
