Daylight savings time ends on November 1st, 2009 at 2am. The time goes back one hour, so if you go to bed at 11pm, turn your clocks back to 10pm.
There's been quite a bit of controversy about daylight savings time and whether we really need it at all. The modern practise of turning clocks forward at the beginning of spring was originally proposed by George Vernon Hudson, a New Zealand entomologist in 1895. Less daylight early in the mornings and more daylight in the late afternoons benefits retail businesses, sporting events and other activities that rely on daylight to operate.
Back when it was introduced, daylight savings time also cut down on power usage because oler incandescent lighting used a lot of electricity. Auto accidents and fatalities are also reduced when there's more light in the late afternoon and early evening. But in recent years where heating and electricity usage differ greatly from back when daylight savings time was originally introduced.
One industry in particular that would benefit greatly if daylight savings time was done away with is the entertainment industry. Night time venues that rely on darkness, such as music concerts and other outdoor activities would have that extra hour of darkness without it being too late on the clock. Large employers and factories that run 24/7 wouldn't have the inconvenience of changing their schedules twice a year and television and other broadcast media wouldn't have to change their programming schedules.
At any rate, daylight savings time for fall 2009 is just a few days away.If you'd like more information, see Wikipedia's daylight savings time info.
