> I think monotonicity in UTC is important for analytics use cases (such as bucketing). Monotonicity in wall time not so much. Let's say you want to analyse trades in arbitrary intervals. In UTC things would make sense but when you view them in wall time buckets with broken order you could have negative inventory because a sell could come before a buy. But I'm not sure anyone wants this right now and I'm ok dropping it. > > Use case would be something like when do users form a certain country come to my website. Rounding in UTC would be inconsistent. I believe it is a needed feature. > > I'm not sure I understand precisely what you mean, but is that part of an analytics workload? Another example would be creating a histogram of taxi pick-up times in local time. I think we had [local rounding discussion here](https://github.com/apache/arrow/pull/11818#issuecomment-999499229). -- This is an automated message from the Apache Git Service.
