Good day.
While it is technically possible to modify the plugin so it will accept more ingredients, that is something you'll have to be left on your own to do. The function that checks for partial recipe matches only works with 4 items, so if you have it more than that, it wouldn't work without modification.
The best thing for you to do there is to make some intermediate ingredients, which is to say that some of your 6 items could be combined into one item first to get the total number down to four for the end craft. Like, Bone + Water = Broth. Broth + Meat + Vegetable + Milk = Stew.
As for your time question, there are advanced plugin parameters for each recipe, a 'run after', script, which runs after every craft of that item, and a second one that also runs after every craft. You can use those parameters to call the function from your time plugin to advance time, either by a specific amount per craft using the first one, or by a set amount for all crafts, regardless.of what the item actually was via the second one.
I won't be able to help you set that up, but the option is there, and if you know a little bit of JavaScript you can easily pull it off.
