This will make it not insert a leap second. b) Run it with the -x flag so that it always slews the time. The real solution would be to implement Markus Kuhn's UTS proposal (http://www.cl.cam.ac.uk/~mgk25/uts.txt), which is about the most reasonable meshing of the expectation that there are 86400 seconds per day with the fact that there are not. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
