st_atime

         Time when file data was last accessed. Changed by  the
         following functions: creat(), mknod(), pipe(),
         utime(2), and read(2).

st_mtime
         Time when data was last modified. Changed by the  fol-
         lowing  functions:  creat(), mknod(), pipe(), utime(),
         and write(2).

st_ctime
         Time when file status was last changed. Changed by the
         following functions: chmod(), chown(),  creat(),
         link(2),  mknod(),  pipe(),  unlink(2),  utime(),  and

write().

ctime不是create，是change的意思。

注意：

ls 中的时间，是mtime

ls -lc filename       列出文件的 ctime
ls -lu filename       列出文件的 atime
ls -l filename       列出文件的 mtime
