It seems obvious now that you've clarified it. :P Thanks. Though the name is a bit misleading. Maybe it should be called "recurring instants" instead. I can no

It seems obvious now that you've clarified it. :P Thanks. Though the name is a bit misleading. Maybe it should be called "recurring instants" instead. I can now agree that it seems to be nicely thought out, flexible without being overly complicated. However, just like how the duration of the event can be a separate question, so too can the duration between instants and the number of repeats. I think this would be the main reason why it's not widely adopted. There just doesn't seem to be much of a need for a standard representation of durations or recurring intervals/instants.
