Imperative time allows you to enter time value as per your consideration. For example you can enter 1 for 1 hour, 0.5 for 30 minutes, 0.25 for 15 minutes. :) Without imperative time it will restrict you to enter .59 at max i.e 59 minutes.

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.

I also was confused by this option, the ? did not open any info for me.

Perhaps, it could be expressed with a sheet-level Units field, defaulting to Hour, and allowing decimal entry.

Better to call it decimal time

The default time input allows decimal value, but with restriction of .59 at max (59 minutes).
