Time stamps on files using Samba

I need some help. I am a IT Manager that coordinates bug fixes in a product that runs Samba 2.2. My customers--and I--have noticed that the creation and modified time updates simultaneously. On Windows, and other Unix machines, the creation time stamp always remains constant, which it should do.

The engineers are telling me, however, that this a known problem with Samba, and that it no one pays attention to it and that it really isn't important.

Is this really a known problem with Samba? It seems pretty odd that a file written to a Samba based unit can't keep the creation time constant. I am guessing this is just poor programming with our engineers, since they have tried to BS me at other times and I shoved the real problem back in their faces (I am newly hired because the other IT guy didn't know much about computers).

Can anyone tell me if this really true?
