I got the achievement with these times. Also the achievement only unlocked after I went back to the main menu. Out of interested, what light and dark world times have you achieved so far?

Total levels time: 553.715 / 691.800
Light levels time: 198.548 / 276.800
Dark levels time: 296.560 / 355.000

Adding 198 and 296 together gets me 494. The decimals carry it a bit over 495 so maybe the target is a little higher than 495. Where are you getting a total of 553.715 from?

No achievement :/
Exit game, Steam Library -> right click game -> Properties -> Local tab -> Verify integrity of cache files button -> start game.

Should get it at the main menu.

Ha, yeah you're totally right. The game times I posted were from the SMBstats program. Perhaps the substantially higher total time includes times from warp zones or glitch levels perhaps. That's the last time I rely on a computer to do adding up for me, pen and paper all the way from now on!
