Elite Dangerous's ingame universe is set exactly 1286 years in the future, paired to the current date. However this means that leap years occur at the wrong times, offset by two years.
This discrepancy was lampshaded with a one-day ingame event on the 29th of February, 3302. Ricardo Bentonio, a conspiracy theorist, issued an appeal for aid in proving that the day was an anomaly that signalled the imminent destruction of reality. He met his targets, but as noted by the the resulting article, "as of the time of writing, the universe continues to exist".
