This patch series is a POC for timestamps sync between guest and host machines. 
It implelents PTP-like algorithm, using vsock events for getting the current time. 
Best results are achieved when "boot" clock is used on both host and guest when
recording the events.
The patch series depends on Slavomir's changes, introduced by the patch series
"Add VM kernel tracing over vsock sockets"

Tzvetomir Stoyanov (7):
  trace-cmd: Implemented new lib API: tracecmd_local_events_system()
  trace-cmd: Added new option in trace.dat file for negative time
    offsets
  trace-cmd: Fixed logic in tracecmd_read_page_record()
  trace-cmd: Added implementation of htonll() and ntohll()
  trace-cmd: Added user configured clock to the record context
  trace-cmd: Refactored make_instances() and tracecmd_remove_instances()
  trace-cmd [POC]: Implemented timestamps synch PTP-like algorithm,
    using vsock events.
