>Typo: "Eigteen" hours ;-)

Thanks, I have adjusted it.

>As "Today" is still based on your local time zone, perhaps "24 hours" is easier to understand to be different from "Today" than "one day" - and I personally prefer the time-warp way, being in a different time zone.

That is a touchy one. If we do it for that one, we'll have to also do it with "48 hours", "96 hours" and it will become weird for one week and two weeks.
