[jcifs] timezone problems

[Eric]

Attached is another test case that would seem to confirm Julian's 
observations.  This does the following:

1) creates a file on a share via java.io.File with a UNC path.

2) Sets the last modified attribute via File.setLastModified, and reads 
via File.lastModified.

3) Sets the last modified attribute on the same file via 
SmbFile.setLastModified, and reads via SmbFile.lastModified.

4) Sets the last modified via File.setLastModified, and reads via 
SmbFile.lastModified.

5) Sets the last modified via SmbFile.setLastModified, and reads via 
File.lastModified.

Here's what I get when I run this:

Summer is 07/04/2003 15:00
Winter is 01/04/2003 15:00

java.io.File set/read:
07/04/2003 15:00
01/04/2003 15:00

jcifs.smb.SmbFile set/read:
07/04/2003 15:00
01/04/2003 15:00

java.io.File set, jcifs.smb.SmbFile read:
07/04/2003 14:00
01/04/2003 15:00

jcifs.smb.SmbFile set, java.io.File read:
07/04/2003 16:00
01/04/2003 15:00


We appear to be internally consistent, but inconsistent with the 
behavior observed for java.io.File.
