Or at the measly cost of 8 additional bytes, solve the problem well and good for the entirety of the human race :) 128 (unsigned) bits defers the rollover problem for 1e-9*(2**128)/3600/24/365 = 1e22 years, or 770 billion times longer than the current age of the universe. That of course hedges on a 128-bit integer C standard within the next 25 years ;) Best wishes, Mike -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
