Date on timeseries chart in nested historic query showing in epoc time

I’m using 8.0.14.

This is hard to explain but I am pretty sure it’s a bug with how nested queries are processed by timeseries charts.

I have a parent query that’s basically returning a key/value pair. I then have a couple nested queries under that. The data sources are all returning data as expected.

On the designer level I have a timeseries chart that gets its data from one of the nested queries. The chart is embedded as an object on the main table and it works. The issue is that the x axis is formatting the date/time in epoc time.

I tried exactly the same thing with a historic data binding on a test report. The only difference is that the data source is not nested. It works.
