The Time stones are the Chaos Emeralds of this game. To get a time stone, you must finish a stage with at least 50 rings and jump into the giant ring at the end of the stage just like Sonic 1 . You will then need to complete a special stage.

The stages themselves are unique to other sonic games, the goal is to knock down spaceships in a 3d plane. The first 4 stages are very easy, the last 3 however are pretty difficult and will possibly take multiple tries.

I found that though you can't save when you want like previous Sega arcade titles, you can quit in the middle of a special stage and return from the menu, it won't take you back to the stage before the stage, but it will take you back to the special stage itself! Exploit this to your hearts content. You should have all the time stones by Wacky Workbench 1 or 2
Edit: If you run out of time in a special stage, you will be taken to the next stage and will not be able to return to your special stage save. So if you have less than 10 seconds or 20 seconds when you're above water, pause and go back to the main menu so you don't lose your progress.
