Auto Battle released: Dec 5th 2017.
Game came out: 17th April 2012.
Time without Autobattle: 2,058 days (Converts to: 5 Years, 7 Months, 2 Weeks, 5 Days, 22 Hours, 6 Minutes and 40 Seconds)
Time with Autobattle: 1,484 days (Converts to: 4 Years, 3 Weeks, 2 Days, 23 Hours, 59 Minutes and 59 Seconds)

Just need another 1 Year, 6 Months, 3 Weeks, 5 Days, 8 Hours, 39 Minutes and 59 Seconds before we'll have been playing the same amount of time with AutoBattle as the time we've had without it. (Which calculates to July 24th 2023)
