When Org automatically computes a time interval which is negative, it is off by 1 hour. (This may or may not be related to Chris Willard's "1 hour earlier" problem.) Positive time intervals seem okay. I'm using 6.08c on GNU Emacs 22.1.
To reproduce: emacs -Q Start with this line: CLOCK: [2008-10-16 Thu 10:00]--[2008-10-16 Thu 10:00] => 0:00 Position point over the "00" in the second timestamp. Press S-down. See CLOCK: [2008-10-16 Thu 10:00]--[2008-10-16 Thu 09:55] => -1:55 _______________________________________________ Emacs-orgmode mailing list Remember: use `Reply All' to send replies to the list.
