Daylight saving time springs forward this Sunday, but the future of this time switcharoo in California is uncertain.

Last November, 60 percent of voters approved a proposition which states that Californians want to keep daylight savings time permanent -- with no more time shifts.

But the state legislature must first pass a bill which would officially end the time change in California, and that bill must pass by a two-thirds margin.

Supporters of the bill say it's healthier for sleep patterns to maintain consistency, but opponents say it forces children to walk to the bus stop in the dark.

The bill is in committee in the state capitol. Even if the legislature passes the bill, Congress would have to approve it.
