So i was a newspaper copy editor for a number of years and asked several people in the industry the following question but never got a definitive answer.
How do you differentiate the the first hour of 1 a.m. and the second hour of 1 a.m. at the end of daylight saving time? For example: my wife just had twins, the first girl was born Nov. 3 at 1:59 a.m. and the second girl was born five minutes later at 1:04 a.m. That sequence is understandable but how do you clearly express one time of birth without referencing the other?
