Here's the answer...
Little Samuel Peterson was born at 1.39am on Sunday, November 6.
He was followed 31 minutes later by his twin sibling Ronan, at what would have been 2.10am.
However, at 2am that morning, the clocks went back an hour, meaning Ronan was actually born at 1.10am, according to the official record, making him older on paper than Samuel.
The clocks went back a week later in the US than in the UK, where it happened on the last Sunday in October.
