The obscured timeline you put together the morning after consuming large amounts of chronic.
John: Did I have sex with Alex's girlfriend, Sam's girlfriend, and Jake's girlfriend last night?
Ashton: No, thats just your chronicology.
John: Then what happened?
Ashton: You had sex with Jake's girlfriend, then Alex's girlfriend, and then Sam's girlfriend.
The science of predicting the future, or the actual travel forwards through time to witness it.
I traveled through time to 2050 and was an elected judge presiding over the trial of the descendants of Luke Skywalker who were being held to account for the destruction of the death star. Postmodern Chronology allowed me to witness a hung jury. When the verdict was read and the defendants set free, a group of angry political activists literally hung all twelve members of the jury.
My personal time machine records current events more accurately than any other source on earth. When tested for accuracy my clock will always be right on time. presently the time is now and now is the time. Imagine you read this and ten seconds elapsed. It is not ten seconds after now, it is still now and your imagination has fooled you. Don't be the fool who questions the accuracy of my time machine.
Currently, my records of this event are accurate because I use my infallible personal time machine called Modern chronology to record it.
