Date values

Using Framework: I’m not sure what happened, but since a few days all values of type date taken from parquet files or duckdb query results are appearing as huge integers - apparently milliseconds since epoch. I’m certain it wasn’t that way when I started playing with observable framework, a couple of weeks ago.

No need to show a test case, you can see it in the examples in the observablehq docs. What’s up with that?

Yes the apache-arrow library has changed this as of version @16. See adopt and document the new apache-arrow date encoding by Fil · Pull Request #1375 · observablehq/framework · GitHub

Alternatively, you can opt to stay with the previous version:

import * as Arrow from "npm:apache-arrow@15";
