You can always check out the time traveler convention later

Apparently, no actual time travelers showed up at the Massachusetts Institiute of Technology's recent time traveler convention. It's hard to tell, though whether or not that means there are no time travelers, they were warned not to show or they just got the time wrong.

The MIT Time Traveler Convention produced more than 400 attendees, but no one claimed to actually be from the future. There were mixed reactions about this; of course, people wanted to see the time travelers, but obviously, chaos could follow if one existed.

I'm not sure of the exact date of the event, but if in the future, you need to go back to visit the convention, I'm guessing you could find the right time.
