As Jan de Wet points out, different strokes for different folks.

It all depends on one's point of view:

If you think "I need a copy of file X on this other system" then you
might expect the timestamp to be the same. If you think "I need to
create a new file on this other system - aha, I don't have to use an
editor, I can copy this one from here" then you might expect a "current"
timestamp.

A comprehensible switch is definitely the right answer.

I'm way too lazy to run experiments, but I would not be shocked if z/OS
FTP's "timestamp" behavior was different for datasets as opposed to PDS
members. Goofy and unexpected, unless, of course, you are steeped in the
history and internal architecture of MVS. The "ISPF" timestamps need to
be made into a z/OS-wide standard, but that's a thought for its own
thread.

Also, as we have beat to death before, all timestamps on all systems
should be stored and transmitted in GMT and displayed in the users'
choices of offsets and formats.

That would seem a reasonable expectation at first, but with various
systems' copy commands you are of course dealing with the same
environment, including timezones.

If you try and extend this to FTP, then you get into the realms of
trying to determine whether the source file was GMT stamped or
GMT/offset/local-time stamped and by how much, and what time do you
therefore put on it.

Also there's the concept that with copy commands the file already
existed on the source (and target) environment; with FTP, by nature it's
a 'foreign' file which didn't previously exist on teh target system.
It's therefore a new creation at the time it was sent.
