Passage: Photographer Annie Leibovitz went to the Lennons' apartment to do a photo shoot for Rolling Stone magazine. Leibovitz promised Lennon that a photo with Ono would make the front cover of the magazine, even though she initially tried to get a picture with Lennon by himself. Leibovitz said, "Nobody wanted [Ono] on the cover". Lennon insisted that both he and his wife be on the cover, and after taking the pictures, Leibovitz left their apartment at 3:30. After the photo shoot, Lennon gave what would be his last interview, to San Francisco DJ Dave Sholin, for a music show to be broadcast on the RKO Radio Network. At 5:40, Lennon and Ono, delayed by a late limousine, left their apartment to mix the song "Walking on Thin Ice" (an Ono song featuring Lennon on lead guitar) at the Record Plant Studio.

Question: at what time did John lennon and Yoko Ono delayed their limousine?
5:40
