I agree - Kristján pointed out that you can ensure that backward jumps
never occur by implementing a cache of the last value.

I'm baffled as to how you even identify "forward leaps". In relation
to what? A more accurate time source? I thought that by definition
this was the most accurate time source we have!

+1 on a simple time.steady() with guaranteed monotonicity and no flags
to alter behaviour.
