The American law by which we turn our clock forward in the spring and back in the fall is known as the Uniform Time Act of 1966. The law does not require that anyone observe Daylight Saving Time; all the law requires is that if we are going to observe Daylight Saving Time, it must be done uniformly. http://answers.firstgov.gov/cgi-bin/gsa_ict.cfg/php/enduser/std_adp.php?p_faqid=6880
