Could you maybe allow fractional hours?
That should be easier than adding minutes, and I don't think anyone will want granularity beyond ½ hour.
I suppose that this would only require changes in the input parsing, but maybe your graph formatting would need changes too.
In any case, this is just an idea and it can wait.
I might contribute if I have time once your code is a bit more clean and stable :)
