I'm familiar with hopper clocks, but i've not played around with them too much. I'm working on a design that needs a row of dispensers to fire off every 19 minutes (to flush baby villagers out of an infinite breeder). Will any hopper clock work for this?
If I understand it right, the time interval is based on the number of items passing between the hoppers, so any idea how many items would set it for 19 minutes?

I would line up three 5-minute item despawn clocks (hopper spits a junk item onto a pressure plate). Items despawn in 5 minutes, so that's 15 minutes. It's a little faster than necessary, but still probably suits your intended purpose. If you really want 19 minutes, maybe put a 4 minute hopper timer on the back end of that sequence.
