I am trying to get Last modified dates of Folders and Files mounted on Azure Databricks.
I am using following Code:

root_dir = "/dbfs/mnt/ADLS1/LANDING/parent"

def get_directories(root_dir):

    for child in Path(root_dir).iterdir():

        if child.is_file():
            print(child, datetime.fromtimestamp(getmtime(child)).date())
            print(child, datetime.fromtimestamp(getmtime(child)).date())
The issue is that it is giving wrong dates for some folders.
When I put a wait time of 1 second (time.sleep(.000005)) for each iteration, it gives correct results.
Otherwise, it sometimes give current date or date of folder listed from last iteration.

Seems, when the processing is fast, it is not able to pick correct modified date.

I have explained this issue on other portal:

Adding further details:

from os.path import getmtime
from datetime import datetime
from pathlib import Path
import time

Operating System: Ubuntu 18.04.5 LTS
Python: 3.8.8

It probably has nothing to do with your bug, but your title is wrong. You are _not_ getting mtime using pathlib (but using os.path instead). That is done like using this approach:

Just to eliminate irrelevant details, could you try _actually_ implement the algorithm using the above, and see if the results differ?

Updated title. As I used getmtime of os.path module.

Thanks Vedram for the response. Changed the title.

But I get the same issue with Path.stat().

When I put a sleep time for each iteration, it works fine. Else, it gives current date as modified date.
