I only care about coarse grained time tracking on my team. I estimate to the quarter day at the smallest, if any task is smaller than that, it shouldn't be a separate WBS item. After all, my end-of-year bean-counter statistics are all based on person days anyways, and I'm not a consultant, so why would I care about tracking to the 15 minute increment?
