Want to be careful here, does it matter that `os:timestamp/0` is not
monotonically increasing?
Especially worrying is that on Windows, `os:timestamp/0`'s microseconds is
always zero, so we really need to be careful about just pushing into this
instead of perhaps `erlang:timestamp/0` or [following the
manual](http://erlang.org/doc/apps/erts/time_correction.html#how-to-work-with-the-new-api)
keeping in mind we need to support down to Erlang 17 at the moment.
