Ok, makes sense if it works. I did not notice the regexp option.
I do have this now:

~header "Date" regexp "."
execute "/usr/lib/claws-mail/tools/fix_date.sh %F"

But it does not work. Are scripts not allowed to modify messages from
processing rules?
And would it make sense to allow actions for processing actions?

And even more important... If a local file changes, can I sync it back to the
IMAP server automatically?
