I was just wondering whether there is a way to make the timestamp received in XDP/BPF via *bpf_ktime_get_ns* comparable with the usual functions in user-space such as *clock_gettime(CLOCK_MONOTONIC, &t);*? Unfortunately, *ktime_get_ns* is defined as the time since system boot, but as far as I know, there is no way in user-space to determine the time since system boot any finer than in seconds.
