NFS atime

[jesk]

Hello, can somebody explain me why atime doesnt work over NFS?

Influencing the atime of a file or directory on a nfs mounted filesystem
doesnt work over NFS.
I tested this with FreeBSD4.8, FreeBSD5.2.1 and FreeBSD Releng_5 as client
and FreeBSD 5.2.1 and a NetApp-Filer as Server.
RFC´s 1094(v2) and 1813(v3) implies that atime is beside ctime and mtime a
normal attribute and that there is no exception for it.
