Chagne filename of downloaded planet data into aquisition date

I have downloaded some planet data using the Example-8-:-Multiple-timestamps-data script (link) and that works fine. However, as I plan to download the last 7 days of images, every week, it would be useful to know what date the image was taken.

There is a simlar question here however it uses WmsRequest() and with that solution I am able to open the url in the json that the function (see below) looks at, however the json file that I have does not contain a date aspect in the url. It contains a timestamp, but that is when I created it, not when the image was taken.

How can I adjust this script to change the filename to the acquisition date (or a similar script)?

import pandas as pd

import glob

import json

import datetime as dt

from urllib.parse import unquote



def get_request_dt(request_file):

    with open(request_file, 'r') as req:

        request = json.load(req)

        url = unquote(request['url'])

        time_parameter = [t for t in url.split('&') if t.startswith('TIME=')][0]

        time = time_parameter.split('TIME=')[1].split('/')[0]

        return dt.datetime.strptime(time, "%Y-%m-%dT%H:%M:%S")



if __name__ == "__main__":

    folders = glob.glob('./data/*')

    dates = [get_request_dt(f'{folder}/request.json') for folder in folders]

    df = pd.DataFrame(zip(folders, dates), columns=['folder', 'datetime'])

    df.sort_values(by='datetime', ascending=True, inplace=True)

    print(df.head().to_markdown())
