I have a data file with a field called extraction_time that has fields like below.

..,"extraction_time":"2022-03-15T02:33:39",..

On my crawler I have a Classifier that looks like so:

However, when I look at the table that is created, extraction_time is always of the string type.

How do I ensure that when my crawler creates the table, it identifies the extraction_time field as a timestamp and not a string?

Any help is greatly appreciated
