Use consistent time unit names for our API

What

We have been wildly inconsistent with how we name our time units, and it is time we fixed it. So starting now, we're using:

• secs instead of s or seconds
• nanos instead of ns or nanoseconds
• millis instead of ms or milliseconds

All function and parameters using the old names have been deprecated, and will be removed in a future version.

Why these names?

• They are short without being cryptic
• They are the ones the Rust standard library (mostly) use: https://doc.rust-lang.org/stable/std/time/struct.Duration.html
• Anything is better than being inconsistent :)

found two more incorrect renames, otherwise looking good now!
