When creating a Date object, you can pass the number of milliseconds since 1-1-1970. How would one ever compute such a figure?

What I want to do is compute elapsed days between two dates. If I had relative milliseconds, I could do that. Is there another way to do that?

I mistakenly assumed the setMilliseconds() and getMilliseconds() functions dealt with the 1-1-70 relative milliseconds value. But I now know they are associated with the time value of the Date object.

Is there a way to access the 1-1-70 relative milliseconds of a Date object?

Thanks,
Ken

Use the valueOf property of the Date.

The correct way to do this is to use getTime(), which returns the number of milliseconds since January 1, 1970 at midnight.
