setInterval - time in milliseconds?

When using setInterval, timing is in milliseconds, correct? If I have a movie that is 2 minutes and 42 seconds long and I want it to load another movie when it is finished playing, that would be 162 seconds before I want the second movie loaded.

So I would use 162,000 as the interval timing value right? Or am I going crazy… :look:

Okay I may be going crazy regardless…
