I was gonna say, why not just close all positions and turn off the computers around the leap second? How much are you realistically gonna lose by missing a few minutes of trading, compared to the alternative risk? Edit: I guess the other way to look it is I guess now how much you can make on a few minutes of trading, seeing that it was worth putting at least one software engineer on it for a long time despite the risks...
