In the 1.70 version of the game (can be found in the resources tab), times usually ending in xx.x7 in other versions end in xx.x6. This is time save that IS counted in the leaderboards, thus incase a level you're trying to get a good time on is included in the 1.70 version , you should maybe play on that!

Remember to go to patches and then click browse levels so that you don't have to scroll all the way back down every time you quit to the menu. If anyone is clever enough to fix Happy green hills, please let us know!
