This looks very good and I have tested successfully, but is there a
way I can set the today to automatically become todays date in that

Yes...see the python datetime module[1]...particularly the strftime()
call on date/datetime objects.

I know this will sound like I am being very cheeky, but is there a way
you can make this for where the ftp server is actually windows server?
The script runs and it shows the date the file was modified, but still
downloads them, I have attached the script I am now using with your code in.

logfile.write(ll + '\n')
