Creation of directories with '1899-12-30 00:00' modified date from mirror command (BulletProof FTP Server)

Throwing this out here so that Google knows about it - I have
investigated into an odd rsync error - 'Time value of <directory path>
truncated on receiver.' - and found that it was caused by spurious
modified timestamps on directories that have been created by lftp
(v4.3.6-1, Debian Testing) mirroring a directory from a BulletProof FTP
Server.

It seems that every directory bar one has the '1899-12-30 00:00'
modified date (which will naturally cause rsync to choke).

Logging in manually and listing the home directory:

==================================================================

drwxr-xr-x   1 ftp      ftp             0 Jul 19 13:49 <directory>
drwxr-xr-x   1 ftp      ftp             0 Jul 17 21:07 <directory>
drwxr-xr-x   1 ftp      ftp             0 Jul 19 16:31 <directory>

==================================================================

Clearly the year is broken here. FileZilla doesnt seem to mind and
returns 2012 during testing.

Please turn on debug in lftp (command "debug") and see what the
server returns for MDTM command.

Here is the output for logging in and listing the home directory:

As you see, the ftp server returned the year 1899. So it is the server
to blame.

You can turn off using MDTM in lftp by this command: "set ftp:use-mdtm no".

Ah, I wasnt expecting to understand the protocol so glossed over the 
number. With mdtm off junk is still returned, so I will just tell the 
site admin that BulletProof FTP Server is crap.

Thanks
