Please don't modify flush_items(), add everything to print_item().
You don't need this extra boolean flag, just use
if (timestamp_begin == 0) {
timestamp_begin = item->ns;
}
timestamp_end = item->ns;
Have made changes.

I have also added packet_size and content_size in both client and metadata.

Since our binary stream files do not have struct padding so both should
be equal in values.
Have a look.
The clock definitions for the timestamps are not right. I loaded the
trace with Trace Compass and it shows always the same timestamp. For
example in
102-tracing-wget-critical-path/wget-first-call
I get this:
