Uses for access time

[DGD at cup.portal.com]

The most useful aspect of "access time" is for a system administrator.
I was once so unfortunate as to be on a large system where the users
woould squirrel away copies of large programs (.c's .o's .a's ,etc.)
and very rarely use them.  When the disk crunch hit, as it had to, a simple
"find" of files not accessed for 6 months showed about 200 megabytes
of files which were candidates for purging/backup-to-tape/whatever.
    "If you haven't used it for 6 months, you don't need it on-line!"
