You might find bashup.events interesting. Here's a section in a blog post where I ~explained it using an example similar to your timer. (I simplified it for the example, but I use a more complete version of this approach to calculate command duration in https://github.com/abathur/shellswain)

Author here. To give credit where it's due, the event system is from https://github.com/bashup/events, and it's just as useful for writing modular bash in other contexts.

A near non-sequitur per your aside (I agree with the rest...): https://github.com/bashup/events is one of my favorite little things. I even blogged about it in January!
