That's very different from the idea that an email
client is "rubbish" if it doesn't do it. I have OE and
TBird here. Neither one sets to mod date. Not that
I'd mind if they did, but I can't say I'd ever noticed
one way or the other. If someone sends me a photo
of their new baby it's not particularly relevant to
me what day they took the photo.

And the date-of-taking would probably be embedded in the file anyway,
these days (and for the last several years).

To give it the same creation time is to say that
both files are the same file; that there are no
actual copies and therefore the copy
was never actually created. Thus it's only an
alternate manifestation of the same, exact item.
Sounds like some pretty funky, existential hocus
pocus to me.

I can have two (or more) copies of the same file, _with the same date
stamps_, on the same disc, as long as they're in different directories;
nothing existential about that. I can even have them in the same folder,
provided I have changed the filename for one of them. Whether they're
"alternat[IV]e manifestations" I'll leave to the metaphysicists, but
they both occupy (separate) space on the disc, i. e. I'm not talking
about links, pointers, or such concepts.
