Daylight saving time ends tonight. Here's when to set your clocks back

Daylight saving time officially comes to a close before dawn Sunday. Clocks fall back one hour at 2 a.m Nov. 1, meaning people get an extra hour of sleep. It also means there will be more light in the mornings now, and it will get dark earlier in the evening. Most cellphones make the change automatically. People with analog clocks should set them an hour earlier manually. While many will welcome the extra sleep, others may have hoped we'd have seen an end to this twice-annual clock changing practice by now. Daylight saving was first adopted in the U.S. through the Standard Time Act of 1918. Numerous efforts over the years have sought to put an end to it. A bill moving through Congress called the Sunshine Protection Act revives an effort to make daylight saving time permanent, although it's unlikely to pass this year.
