Time is a 1973 Pink Floyd song from The Dark Side of the Moon, the fourth track on the album. The lyrics by Roger Waters meditate on the passage of time, inspired when he realized in his late twenties that life was happening now rather than being something to prepare for later. The opening clocks and alarm sounds were recorded in an antique shop for a quadraphonic effect, a idea credited to Alan Parsons; the track features a long drum segment by Nick Mason and a bass tick-tock by Waters. The song is in F sharp minor, with David Gilmour on the verses and Richard Wright on the bridges with female backing voices, and it is the only track on the album to credit all four members for songwriting. It was released in the United States as a single in 1974 with Us and Them as the A-side, and the album includes a Breathe reprise. In 2023 Roger Waters released a re-recorded version on The Dark Side of the Moon Redux, a slower, more atmospheric interpretation not featuring the other original members.
