Using computers clock to call functions

I need to use the computer clock to load a function in a given time in milliseconds after the application has started. How do I do that?

Use can use setTimeout() function or Timer class.

Those are heavily affected by memory usage and I am loading videos.

I figured out a way using date() but it is still affected by memory when the memory load is too heavy.

Well getTimer() tells you how many milleseconds since the application started.

I ended up just using cue points.
