What is the type of duration?

[TornaxO7]

Hello! Currently I'm getting the following error messages:

5 │    :time-range 10
  │                ── `10` is not of type `duration`

But changing it into 10.0 doesn't work either:

5 │    :time-range 10.0
  │                ──── `10.0` is not of type `duration`

what should I enter in duration then?

A time followed by an s (seconds) or maybe ls (milliseconds) in a string
