Inaccurate time reported

[jpuffer]

Non-round second inputs will produce inacurate results. For example, 70 outputs 1 minute where it should output 1 minute and 10 seconds (or there should be an option to not 'round' the data and render remainders down to the smallest time increments)

readableTime is fuzzy by design (as you can see in the specs). It's similar to the way that GitHub displays time on comments. I'd like to keep this project simple, so I don't think I'll add precise time as a feature.
