Time tracking for custom objects

Ability to track time on any object/task/event, this is different then planning as it gives a planned vs actual view, tracking will give the user an idea of how long they spend on different life areas, on different projects or whatever they want to track, optimally it would also feed an algorithm/ai that can help estimate or suggest workload and duration of events, a stats UI will provide data of how the user is spending their actual time, connection to llm will provide insight about procrastination or follow through on plans etc.
