Hitchhiker Guide to the Galaxy has this to say about the Last Great Time War: it happened. Which is more that could be accurately asserted on the topic of the Absolutely First Time War, ChronoWars and Tempus Bellum. Details are currently unavailable. The occurrence itself was muddled by various party breaking out of Time Lock or entering closed and sealed events to such extent that even those who were there not sure if they were. Even those who tried to understand or at least explain the situation to half-million stadium on Graak Six eventually talked themselves into such nonsense that no one would believe them even with 70 percent discount due to them being chrono-historians and thus scienter certified mad. Most likely you will be born, live unhealthy life and die without even realizing that the Last Great Time War actually happened. Hint: as matters of courtesy don't mention it in front of Daleks, Time Lords and they associates. Er, and good luck with not locking yourself inside that nasty historical mess. And even if you do, remember, don't panic!
