When Xander, Cordelia and Willow come up with a plan on how to defeat The Judge, Xander tells Cordelia to meet him at Willows house in half an hour whilst Willow is getting Oz to bring his van so that they can steal the rocket launcher. Bear in mind they said they would do it in HALF AN HOUR.

Then it cuts to Buffy in her bedroom crying and falling asleep. Buffy then wakes up and it is morning and she goes to school to confront Jenny.

The next scene after that we see Xander, Cordelia, Willow and Oz stealing the rocket launcher, but from what Xander said, this should have happen the night before.
