Yes - I ran into the same problem several years back with a Samba 
share used by multiple users to store PVCS files, as well as just 
straight copies of source code.  If one user overwrote a file 
belonging to another, the timestamp got set to the current Samba 
server time, and NOT the actual file timestamp.

Because of this, at the time Andrew Tridgell implemented a fix that 
has been working perfectly for me for the last two years, but which 
to my knowledge has never been documented.

To enable the fix, you need to add "-DUTIME_WORKAROUND=1" to the 
compiler options in the Samba makefile, and then rebuilt Samba from 
the source - i.e. do a "make" and "make install".  To have the change 
actually take effect, you will need to have all your affected users 
log out of the server, and then back in - to ensure that they reload 
smbd from the new binary.

To the Samba team:  Maybe someone can document this fix, or better 
yet, make it an smb.conf option, rather than a compile-time option?

Hope this helps!
