Durée des tâches en heures et pas en jours

J’aimerai savoir si il est possible de donner des durées de tâches en heures et non en jours comme c’est le cas actuellement.
Si cela est possible, comment faire ?

Merci d’avance

Translation gracefully provided by Google Translate:

I would like to know if it is possible to give task durations in hours and not in days as is currently the case.
If this is possible, what should be done?

Thank you in advance

We do not speak French, sorry. Please consider writing in English for better understanding.

Answering to the question: no. This is in the FAQ:

Could you one day add this feature please .

Thank in advance.

Good morning,

Awaiting your reply,
