Question

What does the expression how does time fly mean?

Answer 1

Time flies when you're having fun , or I guess it's ten years since I last saw you—how time flies . This idiom was first recorded about 1800 but Shakespeare used a similar phrase, “the swiftest hours, as they flew,” as did Alexander Pope, “swift fly the years.”

Answer 2

It means that time flows from our hands if sit idle we did not control time but time control us so we do not waste time.
