> The timestamp argument to pn_transport_tick is a pn_timestamp_t.  pn_timestamp_t implies real time (wall clock) in that it's expressed as a time value based on epoch.
> As seen in QPID-6698, using a real time value for that argument can lead to problems if the real time is adjusted (eg.  timezone, daylight savings, drift).
> Instead, pn_transport_tick should be passed a monotonic clock source - one that does not reflect changes in real time.
> All documentation and examples should be updated accordingly.
