SmbFile reports incorrect file dates

When attempting to get the file date from a SmbFile it always returns 0.
Connecting to the same smb share using finder in OSX returns the correct files 
dates.

The share is setup using a samba on a debian based linux box, samba version 
3.6.6 running on a virtual box VM.


Using finder
----------
Server: smb://192.168.56.101/share/file.txt
Created: Today 11:53 am
Modified: Today 11:53 am

Using jcifs
---------
getLastModified() = 0
new Date(getLastModified()) = Thu Jan 01 12:00:00 GMT+12:00 1970
new Date(lastModified()) = Thu Jan 01 12:00:00 GMT+12:00 1970
new Date(createTime()) = Thu Jan 01 12:00:00 GMT+12:00 1970
new Date(getDate()) = Thu Jan 01 12:00:00 GMT+12:00 1970



Below is the unit test I have used:

  @Test
  @Ignore("Dependent on Simons virtual machine")
  public void smbLastModifiedDate() throws Exception {
    SmbFile smbFile = SmbFileUtil.connect("smb://192.168.56.101/share/fie.txt", 
    "", "johan", "cruyff");
    
    System.out.println("getLastModified() = " + smbFile.getLastModified());
    
    System.out.println("new Date(getLastModified()) = " 
    + new Date(smbFile.getLastModified()));
    
    System.out.println("new Date(lastModified()) = " 
    + new Date(smbFile.lastModified()));
    
    System.out.println("new Date(createTime()) = " 
    + new Date(smbFile.createTime()));
    
    System.out.println("new Date(getDate()) = " 
    + new Date(smbFile.getDate()));
  }


Can anyone shed some light on this?
