feat: show formatted date instead of epoch on results

[villebro]

SUMMARY

When pressing "View results" on Explore View, the primary temporal column is displayed as epochs. This applies a typical %Y-%m-%d %H:%M:%S format to the __timestamp column to make the results slightly more legible.

Does this table use the new chart data API? What about other datetime columns? If I'm understanding the code right, all datetime columns will return epochs? I think it would be best if the new API response payload will include data type info, what do you think?

And how about replacing this table with the TableChart? There seems to be some overlapping work here.

@ktmud this is only being used on the DisplayQueryButton on Explore View to show what data is coming from the backend. It's being used to display whatever data is coming back from both the legacy and new chart data endpoint. I also believe it doesn't know any context about datatypes, so this is just a quick fix to make chart/data debugging slightly easier.

Oh sorry @ktmud , I hadn't seen that PR, cool! Yeah, let's use that info once that PR gets merged!

LGTM! Thanks for making it human-readable, and thanks for the tests.

Hi guys, i'm pretty new to Superset and have recently upgraded to superset 1.1 and i am getting the UNIX timestamp in filter box. Could you please suggest how to resolve it.

Same problem here

[villebro]

@PiyushGupta3108 @musthak24 this is a known limitation of Filter Box. Since Filter Box is in the process of being deprecated, and the native value filter properly formats timestamps, I don't expect this to be fixed. If you want to enable native filters, just enable the DASHBOARD_NATIVE_FILTERS feature flag in your superset_config.py.
