This keeps true to the idea of HIL HAL HPL separation.  You don't choose the time precision
in advance just because it is an obvious programming snag, you make a HIL program that
converts from other precisions to its standard cross platform precision.
As that cross platform capability gets better with time, you add more to the HIL app,
or create several levels of HIL.

There's no problem having one app that works across several speedy/fancy platforms,
and another that works across those and all the slow and klunky others is there?
