Hello, I have make a server action who create a crm.meeting object at the creation of a project.task.work object. I want to have a single calendar with all "meetings"(holidays, meeting, project task and so on).

But work object has just a duration and a date field, how can I calculate the date_deadline field for meeting object with one datetime and one float.

I remember that for duration 8:30=8,5 in database.

I don't know how to do.
