Most/all datetime are built around the idea very specific timestamps, often with minute or second precision. In some cases we're getting data like "on 2019-07-28" or "1 day ago" which is rather inaccurate. We could try to translate "2019-07-28" into "2019-07-28 00:00:00" but it would be hard to tell if we mean "at some point at that day" or "exactly at this time". "1 day ago" is even worse because this is usually range of "24h-48h59m".
This is a bit of a larger problem/thought.
