stat.2:
st_atime Time when file data was last read or modified.
Changed by the following system calls: mknod(2),
utimes(2), read(2), and write(2). For reasons
of efficiency, st_atime is not set when a direc-
tory is searched, although this would be more
logical.
% touch foo
(wait...)
% cat >> foo
sdf
^D
% !s
stat foo

it seems that access time should have been updated by the call to
write() implicit in the >>. the write(2) man page does not mention
what action it ought to take (which is a bug in itself...).
