I'm afraid this feature does not work yet (at least not with SMB shares):

I suspect the "_" substitution is not happening.

Also, I would prefer if we just have *one* sane format for duplicity
files that works for all filesystems, rather than giving several options
to customize the format. Why not just use

prefix.year-month-day-hour-minutes-seconds.suffix

and skip the timezone part completely (use GMT instead, as discussed
earlier)? And maybe remove the --short-filenames format, as it will then
be useless?

Of course, there would be some need for backwards compatibility. I think
duplicity should automatically detect/read files of both (long and
short) old formats, but create only the new format.
