There was an Alice in Wonderland quality to the Supreme Court Monday morning, where clocks throughout the building were off-kilter — apparently triggered by an unsuccessful effort to turn them back when daylight-saving time ended early Sunday morning.

When the Court convened at 10 a.m. sharp, the ancient clock hanging above the justices read 6:20, as did clocks throughout the building (they’re all controlled remotely, apparently.) Before the first oral argument began, Chief Justice John Roberts Jr. took note of the glitch, though he did not explain it or apologize for it. Court spokeswoman Kathy Arberg said later that a malfunction in the Court’s master clock made it impossible to reset the other clocks in the building.
