Downloading all files older than 3 hours from a ftp-server.

[Thomas W]

I need to download all files older than 3 hours from a ftp-server.
What's the easiest way to this? I've looked into the standard ftplib,
but it seems like the only way to go is to parse the
ftp.retrlines('LIST') command and that seems to be very easy to mess
up. 

any hints? 

Best regards,
