monology/pile-uncopyrighted · Inquiry About Timestamp Information in the monology/pile-uncopyrighted Dataset

I am interested in knowing if there is any timestamp information associated with the documents within this dataset. Specifically, I would like to find out:

Does the pile-uncopyrighted dataset contain any metadata or fields that include timestamps (e.g., creation date, modification date)?

If not, is there a version of this dataset available elsewhere that includes timestamp information?

Alternatively, does the original Pile dataset include timestamp data?

Could anyone provide guidance on where I could find this information or suggest alternative datasets that may meet these requirements?

Thank you very much for your help!
