I'm reading the library reference for
[core.time](https://dlang.org/phobos/core_time.html#Duration)
and It says that the duration is taken in "hnsecs" and I
cannot understand if 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"`.
[1] https://dlang.org/phobos/core_time.html#.Duration.total
It doesn't work for me. I have the following code:
```
MonoTime start = MonoTime.currTime();
// Doing stuff
MonoTime end = MonoTime.currTime();
Duration dur = end - start;
dur = dur.total!"nsecs";
```
and I get the following error message:
"Error: cannot implicitly convert expression \`dur.total()\` of
type \`long\` to \`Duration`"
You cannot change the precision of `Duration`, it always counts
in multiples of 100 nsecs. You can count how many multiples of
other units fit into the same `Duration` using `total`, but it
will just return a number, not a “converted” `Duration`.
`toString` will produce an easy readable string (more or less),
as in https://run.dlang.io/is/baqKLG, where “hnsec” is the
smallest unit. If you think hectonanosecond is a weird unit, then
[you are not
alone](https://forum.dlang.org/post/pwotyniksrskdzmea...@forum.dlang.org), and it [has been pointed out](https://forum.dlang.org/post/khppfxsyfefjksvri...@forum.dlang.org) that it does not comply with SI.
