This makes me realize why there could never be " personal " time travel devices..... You would never again forget or miss anything, you could always just go back and catch it later......get a ticket, go back and leave yourself a not not to speed that day..lol....do something wrong, same thing....boy, we would mess the time space continuum up beyond belief....I dunno,....sorry....just thinking useless thoughts out loud, kinda, sorta....lol
