Iowa Capital Dispatch: Iowa lawmakers are pushing once again to put the state on permanent daylight saving time. Under House File 2331, Iowans would no longer advance their clocks an hour in the spring. Instead, the state would permanently be on daylight saving time, keeping clocks an hour ahead of Central Standard Time all year long. The House voted 82-13 to pass the bill, sending it to the Senate for consideration. The U.S. government needs to grant permission before states can be on year-round daylight saving time. Arizona and Hawaii are on that system.
