sumption;

ious governmental entities at all levels of govern-
ment, and that such energy conservation efforts
could lead to greatly expanded energy savings; and

the public interest, including the reduction of crime,
improved traffic safety, more daylight outdoor play-
time for the children and youth of our Nation, great-
er utilization of parks and recreation areas, expanded

ered to exercise the authority vested in me by section
3(b) of the Act [formerly set out above] to grant an ex-
emption from section 3(a) of the Act (which establishes
daylight saving time as standard time), or a realign-
ment of a time zone limit, pursuant to a proclamation
of a Governor of a State finding that the exemption or
realignment is necessary to avoid undue hardship or to
conserve fuel in the State or a part thereof.
SEC. 2. In deciding to grant or deny an exemption or
realignment, the Secretary shall consider, among other
things, the policy of the United States, as expressed in
sections 2 and 4 of the Uniform Time Act of 1966 (80
Stat. 107, 108; 15 U.S.C. 260, 261), to promote the adop-
tion and observance of uniform time within the stand-
ard time zones of the United States and the conven-
ience of commerce, as well as possible energy savings,
undue hardship to large segments of the population,
and the possible impact on the success of and coopera-
tion with the national energy conservation program.
SEC. 3. In carrying out his responsibilities under this
order, the Secretary shall, as he deems necessary, con-
sult with the Department of Health, Education, and
Welfare, the Federal Energy Office (or any agency
which hereafter may succeed to its functions), and any
other interested agency and he may call upon those
agencies for information and advice. Each interested
department or agency shall assist the Secretary, as
necessary, to carry out the provisions of this order.
