[Samba] Merely Opening Excel Files Increments Last-Modification

Thank you for responding to my post.
As for your question, my concern is not that (as you
put it) "the date of last modification [is] the date
of the file". It is, rather, this:
If today I do "cat file.txt" on a text file whose
last-modifiation date is December 23, 2003, I would
not expect "ls -l file.txt" to display April 17, 2004
as the last-modification date.
Similarly, if right now I simply open, then close an
xls file, without saving any changes, I would not
expect its last-modification date to change to now.
The last-modification date should not change as a
result of just reading the file. There would have to
be some writing too.
Are you saying that MS-Excel is designed so that
reading an xls file in MS-excel actually writes
changes to the file, even if the end-user does not
save or auto-save any changes?
