DuckDB dates/timestamps are being exported as a number

[benfdking]

Please Describe The Problem To Be Solved

When working with DuckDB, dates/timestamps go through multiple conversions and one of them is to numbers which when you then look at them in a chart, it's much less helpful.

Optional: Suggest A Solution

Pass them through the pipeline ideally as a number so efficient, but make sure that visual tool can parse. If not easy, might be worth just converting to them to rfc339 and then converting back.
