-------------------------------------
Summary: The client and broker heartbeat code can get confiused
when the system time changes
Key: QPID-5865
URL: https://issues.apache.org/jira/browse/QPID-5865
Project: Qpid
Issue Type: Bug
Components: C++ Broker, C++ Client
Reporter: Andrew Stitcher
Assignee: Andrew Stitcher
The underlying timekeeping code in C++ qpid currently uses CLOCK_REALTIME which
is related to wallclock time and can go backwards and skip time forwards
(either due to NTP or administrator action).
This is not ideal because it can cause false timeouts to occur based on the
system time rather than elapsed time.
It would be better for most timing to be based on CLOCK_MONOTONIC which is
steadily increasing time based on the system uptime. That will avoid problems
due to the system time changing.
