Sorry I took a while @jtmoon79 I addressed your comments and rebased to make my commits match @djc's suggestion

@botahamec Do you want to push this PR over the finish line? Please adjust the commits a bit more matching @djc's request, and adjust the type of MICROS_PER_SEC.

Note that we will hopefully merge two PRs the next few days that touch surrounding code: https://github.com/chronotope/chrono/pull/1337 and https://github.com/chronotope/chrono/pull/1385. You may want to wait with rebasing until that is done.

They are merged now.
