"I've never known of an incomplete pass where the clock keeps running."

A clock on the wall kept catching his eye.

And yet the clock kept ticking, Fuller could feel it.

"We worked round the clock to keep on Recovery's schedule."

But the clock kept ticking and then I thought maybe he's not coming.

The clock in the next room kept on making noise.

On the lower right, a digital clock kept a running count of the hour, minute, and second.

His internal clock kept him aware of the passing time.

But let the clock keep running for a while.

The clock kept winding down, the minutes turning into seconds, until finally there was nothing left on it.
