I don't have time to look into this in detail right now. But isn't that
the wrong view?

The precision with float timestamps is still microseconds which you can
easily express in an integer. That the value can be higher is just
because fsec_t for floating points also includes seconds, right? It
shouldn't be too hard to separate those?
