> Key: DISPATCH-1607
> URL: https://issues.apache.org/jira/browse/DISPATCH-1607
> Project: Qpid Dispatch
> Issue Type: Bug
> Components: Tests
> Affects Versions: 1.10.0
> Reporter: Charles E. Rolke
> Priority: Major
> Fix For: 1.12.0
>
>
> This test fails with a dubious indication that delivery arrived before a
> predicted delivery time.
> There is some uncertainty with respect to the test timing declarations based
> on event.reactor.schedule calls with integer timing granularity and the
> connection statistics gathered with Node queries, also with integer timing
> granularity.
> If the connection takes only a few hundred microseconds to start up then the
> router's internal uptime and last delivery times may appear to be a full
> second behind the test times. The router uptime may be 1.999900 S and the
> external test expects >= 2.000000 S and so the test fails. This is normal for
> systems where the times are rounded down to the nearest whole second.
> The fix for this test is to relax the timing limits by one second.
