I read that coroutine *delays* are not precise. What will cause a `delay` to take longer than the specified time?
And do you think this will work to get the actual passed time after a delay (for example for a countdown timer)?

```val timeBefore = SystemClock.elapsedRealtime()
delay(TICK_DELAY)
val timeAfter = SystemClock.elapsedRealtime()
val passedTime = timeAfter - timeBefore```

`measureTime { }` from the stdlib should suit your needs.

If the Dispatcher, or the VM/machine is short on resources, as can be seen when your computer freezes, the actual delay will be longer than requested.

The computer/device going to sleep, or your app being paused can also lead to delay being longer than what requested.
