Due to Daylight Saving Time starting for the US last weekend, all Monday-Friday episodes of The Tonight Show With Jay Leno now air at 10pm instead of 11pm. The 10pm airings will stay until the end of Daylight Saving Time. The change has been brought it to allow the NBC Nightly News to be streamed live on CNBC from the US – which now airs at 10.30pm UK time. Weekend episodes of The Tonight Show and Late Night stay at 8pm and 8.45pm respectively.
