The FTPClient.listFiles uses the ancient LIST command. With the command, it's quite common that the FTP server returns a listing similar to that of the Unix ls command. It displays timestamps with a day precision only, for old files (older than a year).

Nowadays, you should always use the FTPClient.mlistDir, which uses the modern MLSD command that always retrieves timestamps with second precision.

public FTPFile[] mlistDir() throws IOException

Of course, unless you connect to an ancient FTP server, that does not support the MLSD command.

Note that the mlistDir is supported since Apache Commons Net 3.0.
