Daylight saving time became so popular in the U.S. after World War II that it was adopted by individual cities. At one point the twin cities of Minneapolis and St. Paul were on dueling time standards, which helped spur the federal government to enact the uniform schedule 52 years ago.
If Florida decides to stop changing clocks, it would prevent the most curious conflict Prerau encountered when he was a consultant on time change for the U.S. and U.K. governments: the inheritance rights of twins.
What if a mother gives birth when the clock falls back and one twin is born at 1:55 a.m. and the next is born 10 minutes later, which reverts to 1:05 a.m.?
"The times on the birth certificates would show that the second twin is actually the first-born," Prerau said. "British titles and estates are all inherited by the oldest son. This created quite a quandary. These twins could argue their whole lives over who is the oldest."
