1 day project - Can I set Start/End Time instead of Start/End Date?

1 day project - Can I set Start/End Time instead of Start/End Date?

I have to plan a 1 day project. As far as I can see tasks have only dates associated with them, not times.

(Of course I can circumvent that by pretending we have a longer project and assigning different dates to the task, but I'd prefer a clean display)
