If baby A was born first and baby B was born a half hour later, how is baby B the older twin?

That’s the riddle a set of Massachusetts twins born during daylight saving time will forever be able to pose as the ultimate stumper, as a technicality has made the second-born boy the older of the two.

Samuel Peterson was born at Cape Cod Hospital at 1:39 a.m. on Sunday, November 6, 31 minutes before his brother, Ronan, but their entrances into this world were interrupted by daylight saving time, which ended at 2 a.m.

Ronan was born at what would have been 2:10 a.m., but due to the time change, his official birth is 1:10 a.m.

"The clock started spinning backwards,” maternity nurse Deb Totten, who has worked at the hospital for more than 40 years, told InsideEdition.com. “I’ve never known that to ever happen before!”

The change in time has led to some confusion for hospital staff.

“I remember the people saying, ‘what time is it?! What’s the time?’ and I thought ‘What is the problem, there’s a giant clock on the wall!” laughed mom Emily Peterson, 32, to InsideEdition.com. “I was somewhat preoccupied with the process of bringing them into the world."

My blood pressure had plummeted at one point, so I was sleepy, and it did feel like The Twilight Zone,” she continued. “When I saw the clock, I thought ‘I’m not going to say anything; this is probably in my head.’”

But her husband, Seth Peterson, 43, confirmed that she had not been imagining the clocks spinning.

“My husband was like ‘well this is going to be interesting,’” Peterson said.

So although Samuel was the first twin born, he’s officially younger than his brother, Totten said.

“Legally, we have to have that time [on the birth certificate],” she noted. “It’s something we never see, and I just thought it was an awesome story.”

Now home with their parents and big sister, 2-year-old Aubrey, the twins have quite some time before they begin debating who is older.

“They’ll probably argue about it for the rest of their lives. I just think it’s pretty unique. I’m just not sure how old they’ll be before they understand it — even adults are confused,” their mother laughed.

"I hope they kind of look at it as they’re equally special."
