It appears that the declaration file has:

 

time(value:number, suppressEvents?:boolean):any;

 

but should it rather be:

 

time(value?:number, suppressEvents?:boolean):any;

 

since it functions as a getter as well?

 

the web storm compiler throws an error in the first case, not in the second.

Hi

 

We do not maintain any typescript files. 

I think you will need to contact the person that provided the file.

Those definitions are out of date. I'm working on a new set, but until then, you're going to have to make due with what's available. No getter or overloads were included, so you're going to have to change those. 

// Getter
time(): number;

// And one of these setters
time(value: number, suppressEvents?: boolean): TweenLite;
time(value: number, suppressEvents?: boolean): TweenMax;
time(value: number, suppressEvents?: boolean): TimelineLite;
time(value: number, suppressEvents?: boolean): TimelineMax;

You don't return any because then you can't chain your method calls with the correct type. TypeScript currently does not support returning something like this or self in a definition, so you have to manually write out a return for each type of GSAP instance (TweenLite, TweenMax, etc...)

Here's an example using TweenLite
