加州在規劃廢除日光節約時間：「California could drop Daylight Saving Time」。
A California lawmaker has introduced a bill to unshackle the Golden State from the horological chains of Daylight Saving Time.

Daylight saving time is observed in about 70 countries worldwide, but its benefits are the subject of much debate.

A 2011 study in Indiana found that electricity use rose in the state as a result of daylight saving.
