How old is wumpus? (AW Timezone/Timestamp)

When exactly was wumpus created or what exactly is the wumpus timezone/timestamp, I would like to use it as a timestamp and eventually a timezone. I assume it would be discord's creation/release date, 15 May 2015 according to random internet sources, but I want to get pin point accuracy (to the second) that way I can make it work almost the same as epoch. I am aware this is a stupid idea and I am taking it too seriously, but if someone could get back to me with a proper answer that would be awesome! :) 
Thank you for any help in advance...
