The proposed interface is almost identical in functionality to a userland application doing the following: offset = my_calculate_offset(); clock_gettime(CLOCK_REALTIME, &now); newtime = my_add_ts(now, offset); settimeofday(&newtime, 0); The only difference is that you avoid the error from the delay between the gettime call and the settime call. It just adds the offset directly to the CLOCK_REALTIME. thanks -john -- To unsubscribe from this list: send the line "unsubscribe linux-api" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
