Hi all,

I'm having the same problem referenced in this thread: [Kibana Data Table Date Histogram Aggregation Useless labels](https://discuss.elastic.co/t/kibana-data-table-date-histogram-aggregation-useless-labels/182495/3) - namely, when I split a table and use a Date Histogram aggregation, the column labels appear in epoch time rather than a human-readable format, even when I explicitly specify `format`.

Although, inspecting the response data, I think I see the problem - the formatted date is returned in `key_as_string`, but `key` is still in epoch time. I'm assuming that Kibana is using `key` as the column label rather than `key_as_string`.

Is this intentional, and/or is there a way to force Kibana to use `key_as_string`?

Hi, which version of Kibana are you using? If this is your issue: [https://github.com/elastic/kibana/issues/33010](https://github.com/elastic/kibana/issues/33010) it should be fixed in 7.2.0 and later.

It's 7.1.1, looks like. (We're using AWS' managed ES service, so, we're stuck with whatever they deign to give us.) I'll look around and see if there's a way they allow it to be upgraded.

Thank you!
