NEW YORK (AP) — It’s an idea whose time, as it were, may have come — again. The twice-yearly changing of the clocks in the United States could be a thing of the past if legislation currently in Congress that calls for permanent daylight saving time makes it through.

But even as annoying as some find the back-and-forth of the time shift in the spring and the fall, that doesn’t necessarily mean sticking to one would go over well.

America has tried it before, most recently in the 1970s, and it didn’t last.

Now it’s a new era, one full of people working at home who didn’t before — and advances in sleep science that tell a more nuanced tale.

Could this time (shift) be the charm?

The House of Representatives on Tuesday voted overwhelmingly to pass a bill that makes the shift to daylight saving time, when clocks are moved forward one hour, become permanent.

Currently, the shift is forward in spring and back to standard time in fall as a way to give people more daylight in the summer evenings. But the semiannual change has few fans. An AP-NORC poll last year found that only 12% of American adults were in favor of it, while almost half opposed it.

President Donald Trump has indicated he’s supportive, but it’s unclear whether the legislation will pass any time soon. It faces roadblocks in the Senate, where some Republicans are strongly opposed.

What’s the big deal with changing it?

While people may not like making the change, history shows they also don’t like living with even less morning light in the winter months, when daylight hours are shorter.

In 1973, Congress passed a law instituting permanent daylight saving time for what was supposed to be a trial period from January 1974 to April 1975. It lasted until October, when it was repealed after public outcry. Among the concerns was worry that schoolchildren would start the school day without daylight.

Kevin Birth, a professor of anthropology at Queens College, was in elementary school in New York, at the time. “I had to get up for school and it was like it was midnight,” he said. “It was just pitch black and it remained pitch black into the school day.”

If the U.S. decides to try it again, he said, more has to change than just the clocks. The time zones across the country would need to be adapted as well.

Republican South Dakota Sen. Mike Rounds said that it would be dark past 9:30 a.m. in some areas of his state. “You’d be sending kids to school in the dark,” he said.
