Hi Bastien, I tracked the problem down!
There was a change, in commit b508ff69 two or so weeks ago, to the argument sequence of org-agenda-format-item which I was using to extract the time information from the diary entry so that I could sent that to my Outlook calendar! This meant that I was passing t for the TAGS argument whereas I had intended t for DOTIME. Arghhhh. There's probably an easier way to do what I want but what I have works; obviously fragile but anything to do with Outlook (and MS in general) is fraught with danger... :( Again, my apologies for the noise. Thanks again, eric -- : Eric S Fraga, GnuPG: 0xC89193D8FFFCF67D : in Emacs 24.2.50.1 and Org release_7.9.2-350-g934208
