> 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
> Fix For: 0.29
>
>
> 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.
