Star Supernova

In summary, Betelgeuse is a red supergiant star located approximately 640 light-years from Earth and is the ninth brightest star in the night sky. It is expected to go supernova soon, possibly within the next millennium, and will be at least as bright as the full moon for six weeks. However, it is not expected to cause an extinction-level event on Earth, but could potentially cause some disruptions to weather and technology. It is uncertain when exactly the supernova will occur, but it is estimated to have occurred sometime in the past 639 years. There is currently no way to see the star in its current form without waiting for its light to reach Earth. It is also uncertain if we would be able to detect

So the really lucky folks (for whom Betelgeuse is only visible at night) will get 24 hour days, everybody else will get at least some time with two suns in the sky. The extra hour of light from daylight savings time won't burn the crops, but this might. Probably, all we'll get is visible light (not gamma rays or X-rays), so it shouldn't be an ELE. It's sure going to freak everyone out, though...

Daylight Savings does nothing to add or remove sunlight from crops. Simply offsetting our house clocks doesn't alter the course of the sun.
