I'm reading the library reference for

we can change that and choose the precision. Does anyone know if we
can do that?
It is stored internally in "hnsecs", but you can convert it to other
units using the `total` method [1]; for example,
`myDuration.total!"nsecs"`.

Yes but the resolution seems not to be better than 100 nsecs. A quick
research reveals a better resolution is not possible with common
hardware on at least Linux.
The following program always prints multiples of 100 on my Mint OS:
import std.stdio;
import core.thread;
import std.datetime.stopwatch;
void main() {
auto sw = StopWatch();
sw.start();
foreach (_; 0..10) {
Thread.sleep(0.nsecs);
writefln("%,s", sw.peek.total!"nsecs");
}
}
