Hi Timo.

Wow, that's a strange one.

The test system is Centos 4.3 (Final) running kernel 2.6.9-34.ELsmp #1 SMP.

I tested this with NFS and local ext3.   The mtime is initially set
properly, but gets changed to current system time sometime later on in the
copy process.   I moved the mtime change code around and managed to work
around this, although I'm sure there's a more elegant approach.

The patch is here on the list.
