I haven't seen ones with no times in them... I prefer paper to pc, I think I'd probably double up on entries, writing them down and then putting them on to computer.

I did also just see the 24 hour home layout diary/planner, which literally is 24 hour. I could go down that road, as it has sections for business, family, today's appointments, personal journal space, "would be nice to acheive today" space, shopping list space, etc, as well as reminder words at the bottom of the page; medications, food for the day, exercise, birthdays, special events, and dry cleaning.

Nifty looking thing actually.
