This is mostly correct, except that the access time is not changed if
the file is written, only if it is read.

`ctime' can be thought of as `time of last operation that requires that
the file be backed up'.  A backup program can decide whether a file needs
saving by comparing the file's ctime with the time of the previous backup.
