Trading Hours in Historical Data

I was wondering in the historical data of a min bar chart from AAPL.
I get trading hours from 9:00-24:00+.
What is that exactly?
Trading time is from 09:30 - 16:00 everything before and beyond is trading data from IEX alone ? or from SEC ?
I know pre market and After Hours but until 24:00 it appears to be a very special feature for the historical data.

I am not able to find any information about that.

Hi Alpaca3000
