It would be good to:
Include minutes & hours in the column type for timeline
Add the this timeline as a variable to the Calendar view.
As you can see here. this calendar view allows for you to see when things are due and only does in 30 minute incruments. Having this timeline feature, could allow you to time block. You could allocate specific resources/time to the tasks and keep on track by having longer than 30 minutes. then the time tracking can then once you are working on it, tell you exactly how long it takes. And you can compare the diference. This is really good for planning.
