Prior to version 9.12, we were able to specify interval in seconds for a scheduled event and this is critical for certain features in our application but this is not available 9.12 onwards. It will be extremely useful if that can be brought back.
Also prior to 9.12, we were able to specify the start date/time of a scheduled event giving us flexibility to spread apart the events that run with the same interval e.g. Two events each with an interval of 1 minute, but they could start 30 seconds apart from each other. This too was a very handy feature and will be very useful if it can be brought back.
