...Also, I can't get a higher resolution on the time than whole seconds, that's where the problem is, many times I need to animate 0.3s, so I have to convert frames into fractions of a second.
In animation you think and work with frames. It's the natural way of counting since you got the frames displayed, scrub forward a little bit and you got 4 frames, easy too see and easy to measure. When working with frames fractions of seconds like 0.3 doesn't say anything. it's abstract.
That said I'm sure you can add some equation to genetes on-screen counter to do what you want, I'm just not good enough with math to show you how. (btw, great tip genete!, very useful w. frame-counter in animatics and such).
