The Tennessee House has advanced a proposal that would keep the state on daylight saving time year-round.
Other states are considering similar conditional legislation. President Donald Trump also likes the idea of permanent daylight saving nationwide.
Daylight saving time begins on the second Sunday of March, when clocks move ahead by one hour to allow for more daylight in the evening and less in the morning. Clocks then move back an hour on the first Sunday in November.
According to the bill, the law would take effect on the first Sunday of November after the United States Congress amends or repeals the federal law that requires states to observe standard time. Tennessee would then be able to exempt themselves from observing daylight savings time, but not standard time.
