(a) Duration of period; State exemption
During the period commencing at 2 o'clock antemeridian on the
first Sunday of April of each year and ending at 2 o'clock
antemeridian on the last Sunday of October of each year, the
standard time of each zone established by sections 261 to 264 of
this title, as modified by section 265 of this title, shall be
advanced one hour and such time as so advanced shall for the
purposes of such sections 261 to 264, as so modified, be the
standard time of such zone during such period; however, (1) any
State that lies entirely within one time zone may by law exempt
itself from the provisions of this subsection providing for the
advancement of time, but only if that law provides that the entire
State (including all political subdivisions thereof) shall observe
the standard time otherwise applicable during that period, and (2)
any State with parts thereof in more than one time zone may by law
exempt either the entire State as provided in (1) or may exempt the
entire area of the State lying within any time zone.
(b) State laws superseded
It is hereby declared that it is the express intent of Congress
by this section to supersede any and all laws of the States or
political subdivisions thereof insofar as they may now or hereafter
provide for advances in time or changeover dates different from
those specified in this section.
(c) Violations; enforcement
For any violation of the provisions of this section the Secretary
of Transportation or his duly authorized agent may apply to the
district court of the United States for the district in which such
violation occurs for the enforcement of this section; and such
court shall have jurisdiction to enforce obedience thereto by writ
of injunction or by other process, mandatory or otherwise,
restraining against further violations of this section and
enjoining obedience thereto.
