I think `.nano` is returning something different than what you're expecting. This is the documentation for the function:
```
Gets the number of nanoseconds within the second in this duration.
The length of the duration is stored using two fields - seconds and nanoseconds. The nanoseconds part is a value from 0 to 999,999,999 that is an adjustment to the length in seconds. The total duration is defined by calling this method and getSeconds().
```

It may make more it more obvious if you change your delay to something like 10 seconds instead of 1 second. I suspect you'll see that your printlns don't really change the way I think you're expecting.

It does not make sense to use `LocalDateTime` api to measure this at all. Use `System.currentTimeMillis()` or use `kotlin.system.measureTimeMillis { runBlocking { ... } }`

Yep that works much better :slightly_smiling_face:
