Time Change Spring 2010

 Spring 2010 starts in United States of Arizona............
Daylight savings time 2010 which is the same as what some readers might call 'time change spring 2010' starts on the second Sunday in March and ends at 2:00 a.m. on the first Sunday the 7th day of November 2010. Actually every year the time change will be the same starting in 2007. When the DST ends, clocks should be set back one hour at 2.00 a.m. local daylight time, which becomes 1:00 local standard time.
The observance is based on the law called the Energy Policy Act of 2005. But the individual state can decide whether or not they want to follow the law.  The united States Department of Energy is required to study the impact of use of this Daylight savings time.  If necessary, Congress has the right to make a time change.
