| Doc Text: |
C: The definition for the qpid::sys::Duration(AbsTime&) constructor exposed an internal time value from the AbsTime representation which varied between platforms.
C: A time duration can only be calculated as the difference between two points in time, not just one. What the constructor was doing was not portable between platforms.
F: The definition for the constructor qpid::sys::Duration(AbsTime&) has been removed from the shipped header files and if it has been used it will need to
be replaced.
R: The constructor should now be able to be used between different platforms as expected.
Workaround:
In general qpid doesn't provide timing services and so we do not recommend the use of the AbsTime or Duration classes except where required by other elements of the qpid client API.
However if an application was using this constructor it can be replaced by using the two argument Duration constructor:
old version, which no longer works:
using qpid::sys::Duration;
using qpid::sys::AbsTime;
Duration d(AbsTime::now());
current working version:
using qpid::sys::Duration;
using qpid::sys::AbsTime;
using qpid::sys::EPOCH;
Duration d(EPOCH, AbsTime::now());
