  • Daylight Saving Time
    Daylight Saving Time Beth Cook Information Research Specialist March 9, 2016 Congressional Research Service 7-5700 www.crs.gov R44411 Daylight Saving Time Summary Daylight Saving Time (DST) is a period of the year between spring and fall when clocks in the United States are set one hour ahead of standard time. DST is currently observed in the United States from 2:00 a.m. on the second Sunday in March until 2:00 a.m. on the first Sunday in November. The following states and territories do not observe DST: Arizona (except the Navajo Nation, which does observe DST), Hawaii, American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the Virgin Islands.

  • Daylight Saving Time (DST)
    Daylight Saving Time (DST) Updated September 30, 2020 Congressional Research Service https://crsreports.congress.gov R45208 Daylight Saving Time (DST) Summary Daylight Saving Time (DST) is a period of the year between spring and fall when clocks in most parts of the United States are set one hour ahead of standard time. DST begins on the second Sunday in March and ends on the first Sunday in November. The beginning and ending dates are set in statute. Congressional interest in the potential benefits and costs of DST has resulted in changes to DST observance since it was first adopted in the United States in 1918. The United States established standard time zones and DST through the Calder Act, also known as the Standard Time Act of 1918. The issue of consistency in time observance was further clarified by the Uniform Time Act of 1966. These laws as amended allow a state to exempt itself—or parts of the state that lie within a different time zone—from DST observance. These laws as amended also authorize the Department of Transportation (DOT) to regulate standard time zone boundaries and DST. The time period for DST was changed most recently in the Energy Policy Act of 2005 (EPACT 2005; P.L. 109-58). Congress has required several agencies to study the effects of changes in DST observance. In 1974, DOT reported that the potential benefits to energy conservation, traffic safety, and reductions in violent crime were minimal. In 2008, the Department of Energy assessed the effects to national energy consumption of extending DST as changed in EPACT 2005 and found a reduction in total primary energy consumption of 0.02%.

    HOUSE OF REPRESENTATIVES FINAL BILL ANALYSIS BILL #: HB 1013 FINAL HOUSE FLOOR ACTION: SUBJECT/SHORT Daylight Saving Time 103 Y’s 11 N’s TITLE SPONSOR(S): Nuñez; Fitzenhagen and others GOVERNOR’S Approved ACTION: COMPANION CS/CS/SB 858 BILLS: SUMMARY ANALYSIS HB 1013 passed the House on February 14, 2018, and subsequently passed the Senate on March 6, 2018. The bill declares the Legislature’s intent to observe Daylight Saving Time year-round throughout the entire state if federal law is amended to permit states to take such action. The bill does not appear to have a fiscal impact. The bill was approved by the Governor on March 23, 2018, ch. 2018-99, L.O.F., and will become effective on July 1, 2018. This document does not reflect the intent or official position of the bill sponsor or House of Representatives. STORAGE NAME: h1013z1.LFV.docx DATE: March 28, 2018 I. SUBSTANTIVE INFORMATION A. EFFECT OF CHANGES: Present Situation The Standard Time Act of 1918 In 1918, the United States enacted the Standard Time Act, which adopted a national standard measure of time, created five standard time zones across the continental U.S., and instituted Daylight Saving Time (DST) nationwide as a war effort during World War I.1 DST advanced standard time by one hour from the last Sunday in March to the last Sunday in October.2 DST was repealed after the war but the standard time provisions remained in place.3 During World War II, a national DST standard was revived and extended year-round from 1942 to 1945.4 Uniform Time Act of 1966 Following World War

  • Is Year-Round Daylight Saving Time a Good Idea? Maybe Not
    SenatorReady_FAV_SB0517 Uploaded by: Senator Ready, Senator Ready Position: FAV March, 05 Senate Bill 517: General Provisions - Standard Time - Year-Round Daylight Saving Time Chairman Pinsky, Vice Chair Kagan, members of the Committee, I am here today to present SB 517 which would signal Maryland’s desire to remain on Daylight Saving Time year round. To date, forty-two states are entertaining or have passed legislation on the issue while two—Arizona and Hawaii—only observe their respective standard times. Daylight Saving Time was initially implemented during World War I to save energy, but maintained unexpected popularity among Americans after the war, and was re-introduced year round during World War II for the same energy saving reasons.1 However, with the technological advances we have realized today there is no significant energy saving associated with the time change process. What has not changed, on the other hand, is the continued popularity of Daylight Time among Americans and their desire to make it permanent. The Federal Uniform Time Act of 1966—which codified Daylight Saving Time at the federal level—has been amended twice; both times extended the Daylight Saving period. The most recent change was a 2005 amendment which took effect in 2007. These changes to the original Act demonstrate the flexibility of time adjustment and offer precedent when considering changes at the state level. The Federal Uniform Time Act currently allows states to adopt the Standard Time of their current time zone, but not Daylight Time. The purpose of passing this bill would be to add our name to the list of states asking the federal government to amend the Act and allow us to adopt Daylight Time permanently.

  • C:\PWO Projects\Clients\Time Zone Related\St. Joseph County Time
    A REPORT ON THE UNITED STATES DEPARTMENT OF TRANSPORTATION’S RESPONSE TO SAINT JOSEPH COUNTY, INDIANA’S 2005 TIME ZONE PETITION ADVISORY COMMITTEE ON THE TIME ZONE 3 November 2010 A. INTRODUCTION The Advisory Committee on the Time Zone for St. Joseph County has been asked to consider possible courses of action open to prospective proponents of Central Time for the region surrounding and including St. Joseph County, Indiana. As part of our response we have prepared this report as a primer on time law, Congressional time policy, and the methodology employed by the Department of Transportation (DOT or Department) in time line location proceedings. From our review of time zone boundary decisions and the history of time keeping in the United States we have concluded that the Department initially employed an ad hoc approach to petitions for changes in time zones originating from Indiana in 2005 and persisted in this ad hoc approach with respect to St. Joseph and Marshall counties through the conclusion of the 2005 process. This approach was inconsistent with the seeming focus of the DOT “Procedure for Moving an Area from one Time Zone to Another” (the “Procedure”).1 The inconsistencies emphasized procedure over substance and likely flowed from Indiana’s reputation for time zone controversy and from St. Joseph County’s pivotal political and geographic position. The DOT may be tempted to repeat this approach should a renewed petition originate from St. Joseph County. We also concluded that the Procedure is legally problematic. The bases for, and ramifications of, our conclusions are explored in depth in this report.

  • Transmitting Time of Day Using XDS Packets
    Application Note 3 Transmitting Time of Day using XDS Packets 1 OVERVIEW This application note describes how to properly encode Time of Day information using EIA-608-B Extended Data Services (XDS) packets. In the United States, the Public Broadcasting System (PBS) Television network and its affiliates have been providing this information to the viewing public since the mid 1990s. The application note is written in a tutorial format in order to give Engineering and Operations personnel an understanding of time, time zones and daylight saving time concepts, as well as how this information is encoded into the XDS packets. The application note also provides step by step procedures for setting up the Evertz 8084 and 8084AD Caption/XDS encoders (referred to generically as 8084AD throughout this document) and the Evertz MetaCast 2 software to accomplish this. 2 WHAT IS THE CORRECT TIME ANYWAY? 2.1 UTC AND TIMEZONES Prior to the late nineteenth century, time keeping was a purely local phenomenon. However, once railroads began to operate and move people rapidly across great distances, time became much more critical. In the early years of the railroads, the schedules were very confusing because each stop was based on a different local time. The standardization of time was essential to efficient operation of railroads. In 1878, Canadian Sir Sanford Fleming proposed the system of worldwide time zones that we use today. He recommended that the world be divided into twenty-four time zones, each spaced 15 degrees of longitude apart. Since the earth rotates once every 24 hours and there are 360 degrees of longitude, each hour the earth rotates one-twenty-fourth of a circle or 15° of longitude.
