Well, then, to give you a piece of anecdotal evidence; my experience where I currently am is that we never talk about how long it'll take, unless it's so small and trivial we can say "Give me an hour and I should have a first pass in place". Even then we're not saying it's ~done~, just that we're familiar enough with the code that we can get some prototypal code in place in a time frame. When actually estimating tasks, it's purely point based, and then those can and do vary with how much time they actually eat up, but tend to average out just fine.
