Benefits of having periodical events:

• the same EventId can refer to a series of events
• interval is more accurate

Rescheduling in callback is possible, but:

• EventId changes
• user code must account for time spent in the callback

Interval is never accurate, but only approximate. Precision is always depends on many parameters, including current system load.

Is there a single use case for the need to have the same EventId to refer a series of events? The same variable can be used to represent series as well. The difference is just a little bit more overhead.

There is significant complication of the scheduler code to handle both normal and periodic event.

The Scheduler itself can handle just one-off events.

A wrapper can provide periodical events (with a different EventId type, and better precision), but it's not needed at this time.

I know that repo-ng uses periodic event. I will update repo-ng code before this issue is closed.

Actually, I'm wrong. repo-ng was using periodic event before, but this already has been fixed. So, I don't know any blocks for this issue.
