Ken Giusti created QPID-6699:
--------------------------------
Summary: Improve/clarify the qpid::sys::Time interface
Key: QPID-6699
URL: https://issues.apache.org/jira/browse/QPID-6699
Project: Qpid
Issue Type: Improvement
Components: C++ Broker, C++ Client
Affects Versions: qpid-cpp-0.34
Reporter: Ken Giusti
Assignee: Ken Giusti
Fix For: qpid-cpp-next
Gordon Sim raised a suggestion during a review of a patch for QPID-6698:
"I do also think that the Time.h should be modified/augmented somehow to make
issues like this clearer. E.g. a Duration::FromZero() alongside the FromEpoch
with clear advice as to which to use when? The AbsTime::epoch() method
subtracts a FromEpoch duration, computed using the realtime clock, from the
now() which is computed from the monotonic clock. Is that even valid? These are
arguably separate issues though, just raising tnem for debate."
I'd like to see the interface changed as per Gordon's description. Clarify
which APIs deal with realtime (wall clock) and monotonic clocks.
