Most problems are pretty quick to solve, maybe 30-60 minutes. Scheduling that time every day can be tough. Some problems are pretty tricky. I still haven't solved all of 2017's, "some offset delay" indeed. I might not have solved all of 2016's for that matter - the closer it gets to Christmas, the less likely I am to touch a computer at all.
