On Friday, the FCC issued a Public Notice providing guidance for pre-sunrise and post-sunset operations during March 2008 by AM stations in areas with Daylight Saving Time (DST). Congress, as part of the Energy Policy Act of 2005, passed a law extending daylight saving time (DST) by a total period of four to five weeks.

The FCC issued this statement:

"Daylight Saving Time (DST) commences at 2 a.m. on March 9, 2008. Certain AM stations currently operate with Presunrise Service Authorizations (PSRAs) and Postsunset Service Authorizations (PSSAs). Licensees with PSRAs and PSSAs located in communities with DST should use the April DST 'Advanced' powers and time periods for the period between March 9, 2008, and March 31, 2008. This adjustment is necessitated by the enactment of the US Energy Policy Act of 2005 which extended the effective period for DST into March for the first time."
