>Description:
ls -l shows the following for files, which cannot be backed up by tar, unless they are `touch`ed first.

-rwxr--r--  1 nobody  wheel   918M May 28  60056 seismic0001000.1

Most files have the correct output of:

-rwxr--r--  1 nobody  wheel   918M Mar 17 07:12 seismic0001100.1
-rwxr--r--  1 nobody  wheel   2.3K Jun 21  2006 seismic0001100.sdd
-rwxr--r--  1 nobody  wheel   1.5M Dec 14 08:25 seismic0001300.knx


>How-To-Repeat:
I have been unable to recreate this problem with any regularity, but it appears to occur somewhat at random, to very few files over time. I will post a followup, when and if I am able to recreate the problem on demand.
