If I ignore that timezone stuff for now, this is an example of what it
would look like:

{"time":"2014-02-07T17:15:28.972757Z",...

Code:

static void CreateTimeStringISO(struct timeval *tv, char *buffer, size_t
buflen)
{
    char local_buf[64];
    time_t time = tv->tv_sec;
    struct tm local_tm;
    struct tm *t = (struct tm*)SCLocalTime(time, &local_tm);

    strftime(local_buf, sizeof(local_buf), "%FT%T", t);
    snprintf(buffer, buflen, "%s.%06uZ", local_buf, (uint32_t)tv->tv_usec);
}

Thoughts?
