The idea of expressing 15 minutes as 0.25 is useful. “Imperative time” is a terrible name and I suspect the product of some misunderstanding or translation error. There should be a slider button and it should say “6 min/0.1 hrs” or similar.

Not necessarily 15 mins as 0.25, the time can be express in any form.
