A hundred nanoseconds would be a deci-microsecond or a hecto-nanosecond.
Both are used, though hectonanosecond seems to be more popular, both
generally and with programmers. For example, Apple's Network Time
Protocol
codebase uses the unit. I don't find either name horrible and would
prefer
an actual unit of time in TUnit as opposed to a made up name which I'd
have to remember is actually a hectonanosecond. Perhaps this is my
scientific background coming through.
Well, aside from the fact that I think that most people have never heard
of a
hectonanosecond, it's awfully long to type. millisecond and microsecond
are bad
enough. And do you really want to have to use functions like
totalHectonanoseconds()? Perhaps with a good abbrevation... hnsec? I'll
have to
think about it. As words go, ticks is far more pleasant, but it isn't as
precise.

Well, if you make up a unit, then you can guarantee no one will have heard
of it before. And really, learning the hecto SI prefix means someone will
always understand what hectonanosecond means, as opposed to StdTick or
Duration, etc, which would have a tendency to be quickly forgotten or
confused with another library type from another language. As for typing, I
would expect the 100ns unit to be mainly an internal thing. Most of the
time I deal in microseconds/1000.0 (i.e. floating point milliseconds),
when dealing with std.perf today.
