samba - Mar 2000 - 2.0.6: file timestamps acting strange - even with patch.

> I'm running samba 2.X on Solaris (2.6, 2.5.1), and SunOS 4.X (but
don't
> tell anyone about that last one).
> 
> I had been running samba 2.0.3, and one of my users noticed that when he
> copied a file, using an NT 4.0 workstation, copying a file from an NT
> fileserver (NTFS) to a Samba filesystem, that the dates were wrong on
> the copied file.  In particular, any file with a date older than last
> year seemed to be getting copied with a modified timestamp.  For
> example, files with dates from 1997 were getting written to the samba
> filesystem with a date of December 1999.  This behavior occurred with
> both NT Explorer and the dos box "copy" command.  The problem
does NOT
> occur when copying from a local hard disk: only when copying from an NT
> fileserver!  (Also, the problem does not occur when copying in the other
> direction).
> 
> At first, I found I could fix the problem by setting "nt smb support
> no".
> But I'd like to be able to use the features of Samba 2.X.
> 
> I loaded 2.0.6 on a test system, and the problem went away.  Going
> through the archives, I noticed the patch by Paul Eggert in Digest 2350,
> which solved a different file timestamp problem, applied the patch to my
> 2.0.6.  source, compiled it and installed it.
> 
> After applying the patch (and putting "nt smb support = yes"
back), the
> "copy" timestamp bug is back!  I immediately backed out the patch
> (reverting to the original 2.0.6 source), and the problem went away.

what
