J. McCullough's Golf Ball

Origin
J. McCullough was an avid author and golf player who wrote a science fiction novel titled “Golf in the Year 2000”. In it, the character awakens from a deep slumber in 1892 to find himself on a next millennium golf course. There he witnesses scorekeeping clubs, driverless caddies and jackets that yell “fore”. McCullough predicts advancements such as bullet trains, digital watches, television, conversion of the British pound to coin, chemical warfare and moon travel but never imagines heavier-than-air flight. Another prediction was the rise of women to powerful positions in finance and government, humorously freeing up more time for men to golf.

Effects
Teeing off will create a proximity-based time-effect. It will fast forward an area the size of several large golf courses to some point two centuries in the future. All the present people, technology and buildings caught in the field will behave according to the norms and expectations of the future date. The effect last for only 108 minutes, after which the changes dissipate and revert back to normal. People take a longer time to readjust and will still believe they are in the future, struggling to interact with the present.
