Gametime 9/21

So the Astros schedule says 1:10pm. MLB website says 6:10pm. MLB Ballpark app says 6:10pm. StubHub says 1:10pm. Anyone know what the actual game time is? Going to one of those games and if it's at 1:10 it'll be the game I go to. If it's at 6:10 we'll be going saturday 20th instead. Any help appreciated!
