[Samba] My Samba share changes the timestamp when copying files to it.. (Preserve Time)

[MC M]

I have a Samba share on a Fedora Core 3. When I copy files to it from my 
windows XP Service Pack 2 box the samba share gives all the files the same 
date/time (the current date and time), instead of giving it the same date as 
the files already have. Does anyone know how to solve this problem. I want 
to Preserve to original time and date stamps.

I'm running: Samba version 3.0.8pre1-0.pre1.3 on Fedora Core 3 64-bit Athlon 
version.

Some of my smb.conf file:
[global]
workgroup = MYGROUP
[fileserver]
comment = fileshare
path = /shares
public = yes
printable = no
read only = no
dos filemode = yes
writeable = yes
create mode = 0666
directory mode = 0777
