I haven't actually time traveled (other than my daily commute to work) since the Temporal Cold War. The main reason is that, even though the war is over, it is still happening in the future, which I can't explain.
Well, my great grand father, Kilowatt the third might be able to (he is named the third due to a bizzar accident with a time traveling service on Planet Redmondus (which is of course due to it running windows xz). The program tried to compute the answer to an unanswered question due to a glitch in its pipes screen saver that was running on the terminal)
And, yes, I did (or do, depends on your view point and temporal off set) read The Hitch Hiker's Guide to the Galaxy...
See, I was reading it, then I put it down, and went back in time, so therefore, I have read it, just not yet.
(more medication to follow, Scruffy, you were right, I went by the wrong clock and under-dosed my self with the hyper-spray)
