bullet::::- u.s. president lyndon johnson signed the 1966 uniform time act, setting a common date (the last sunday in april) for all states in the u.s. to set their clocks forward one hour, beginning on april 29, 1967, and to set clocks forward one hour on the last sunday in october, starting in 1967. at the time, 18 states observed daylight savings time (dst), 14 switched time zones rather than changing their clocks, and the other 18 left the option up to their local governments. before the uniform act was passed, the prescribed days for changing the clocks varied across the nation; in the state of iowa alone, there were 23 different dst periods.

many people believe that daylight savings time was first created for agricultural or inter-state commerce purposes, but it was really started by germany and france during world war i in an effort to save coal by reducing energy consumption with a longer day. today, the reality is that this reduction in energy consumption benefit is needed just as much if not more during the winter months than the summer months. in 2018, the european commission performed a public survey and discovered that 84 percent of european citizens were in favor of discontinuing daylight savings time switches. the commission then proposed ending daylight saving time changes as early as this 2019. however, the conclusion of the european commission report only indicated that member states should decide whether to use their current standard-time during winter months or select a different standard-time that aligns to their current summer month's time which would equate to remaining on daylight-savings time year round.
