if the timer softirq doesn't run and wall_jiffies doesn't increase, we won't be able to account for it, so time() will return a time in the past, it will potentially go backwards precisely 1/HZ seconds every tick that isn't executing the timer softirq. I tend to agree for a 1sec resultion that's not a big deal though if you run:
gettimeofday() time()
gettimeofday may say the time of the day is 17:39:10 and time may tell 17:39:09 - 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/
