Presumably so that the OS knows to reserve room in the schedule ahead of time for when the data will be available...?

but without any indication of how much time the process will take to complete, the only thing the OS could do is prohibit anything else from using the CPU between the start time and the deadline, which is almost certainly _not_ the correct thing to do.
