The ideal implementation, in my opinion, would have time stamps defined & stored with time zone information, as given by the user when creating them (although this could default to UTC, say, if not present in the time stamp) but displayed according to the user's $TZ (or overridden with emacs variable) in cases like agenda views. For upwards compatibility, however, it might be best if time stamps with no time zone information be considered to be at the user's timezone, as it is now. -- : Eric S Fraga (0xFFFCF67D), Emacs 25.0.50.1, Org release_8.3beta-1260-gcedef7
