Daylight-Saving Time begins at 2 a.m. Sunday March 10, 2013. So don't forget to set your clocks one hour ahead before you go to bed tonight.
It will last until 2:00 AM on Sunday, November 3.
Keep in mind that some smart phones are set up to automatically adjust for daylight-saving time, so make sure you don't change the time if your phone is going to automatically do it.
In February Sen. Darren Soto filed a bill that would mandate that Florida keep its clock in daylight-saving time year-round.
The Orlando Democrat said he sponsored the bill (SB 734) because he gets frustrated that it gets dark earlier during the winter. The bill is called the "Sunshine Protection Act."
