As you can see, a regular tune up is important to your car's performance. The process should involve replacing the air filter, replacing or cleaning the spark plugs, and replacing the distributor cap and rotor. It can also include replacement of the spark plug wires, fuel filter, PCV valve, and oxygen sensor.
Beginning in 2007, daylight time starts on the second Sunday in March and ends on the first Sunday in November. For a very readable account of the history of standard and daylight time in the U.S., see. Ian R. Bartky and Elizabeth Harrison: Standard and Daylight-saving Time, , May 1979 (Vol. 240, No. 5), pp. 46-53.
Many countries change their clock twice a year to observe day light saving time. The date of Daylight Savings Time Starts and Ends may vary with year to year and also depends on location. In United States DST starts on the second Sunday of March at 02:00 AM. And it ends on the first Sunday of November at 03:00 AM by setting clocks back to 02:00 AM. DST 2015 will begin on 8th March 2015 and will end on 1st November.
