This is the question I woke up wanting answered this morning. I haven’t seen much explanation yet. So I did a little digging, and found this from CBS 13:
The issue will still need a two-thirds vote from the California Legislature and a change in federal law to go into effect. Absent any legislative change, California will maintain its current daylight saving time period (early March to early November).
The proposition’s supporters pointed to a study showing an increased risk of car accidents and heart attacks following the spring change, due to the loss of an hour’s sleep.
Opponents of the proposition argued that even if California voters and the Legislature approve of year-round daylight saving, the hurdle of getting the federal government to approve is too high, considering the state’s tense relationship with Washington. They also say the switch will cause its own headaches. If California goes to year-round daylight saving, the sun wouldn’t rise until 8 a.m. during some winter months, forcing children to walk to school or buses in darkness and likely leading to an increase in car and pedestrian accidents.
No matter which side of the issue you stand on…I thought you would want to know.
