Is this a time or a duration:

How much time does a job like that take?

The term instant needs special attention because its meaning in physics is not quite the same as it is in ordinary language. In physics, an instant is always a time, never a time interval. An instant is a when, not a how long. The phrase at an instant means the same sort of thing as at 2:15.
