In The Big Questions TV series Paul Davies said the following:

“In daily life we all have this overwhelming impression that time is passing. Time flies, as we say.”

“We have this overwhelming impression that time is in some sense moving, that things change. And our whole language, our entire way of thinking about the world, is rooted in this idea of a flux of time. Yet when physicists in the laboratory look to see what causes this flux, when they investigate how we can measure the flux of time, there’s nothing there! Time doesn’t seem to ‘move’ or pass at all.”

“Clocks don’t measure the passage of time! That’s a common fallacy. Clocks measure intervals of time, not the motion of time; just as rulers measure intervals or distances in space, and not speed or motion through space. So I’m not saying that there is no time as such, that time itself is an illusion. Certainly we can measure intervals of time. What we can’t measure is the passage of time. Not only can we not measure it, but many philosophers and scientists argue that time simply doesn’t pass, that our psychological impression of the passage of time is simply an illusion.”

When time doesn’t pass, everything happens now. And all questions are asked in the present moment.
