It's an absolute time stamp, but users of this interface are more interested in the time difference between events and how they change over time. E.g. NTP time stamps are 64bit fixed point values with a 32bit integral part. This is not an interface to read the current system time, so 32bit will continue to work. bye, Roman - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
