Monotonic clock timestamp on packets

Hi.Has anyone looked into timestamping the captured packets using clock_gettime(CLOCK_MONOTONIC, ...)?
I'm thinking adding a struct timespec to struct pcap_pkthdr and filling that in addition to the struct timeval.
For a request-reply situation a monotonic clock is much more reliable than gettimeofday().
