Finally got the time to incorporate your feedback for a v2.
As it turns out, Duration::from_mins/from_hours is actually
still nightly-only...

https://doc.rust-lang.org/std/time/struct.Duration.html#method.from_mins

Anyway, I'll still change these up a bit; I'll use `Duration` for anything
that is a time interval and then use `Duration::as_secs` for
the cycle calculations. This should make it a bit more idiomatic and
less error-prone.
