https://svn.boost.org/trac10/ticket/9489 <p> boost::date_time::time_resolution_traits defaults to boost::int32_t for its v_type parameter. This means that for 64-bit systems, such as time_resolution_traits_bi64_impl and time_resolution_traits_adapted64_impl, date-times whose seconds count exceed the int32_t limit will overflow, returning a negative value for boost::posix_time::time_duration::total_seconds. </p> <p> The attached file reproduces the issue. The output on a 64-bit Intel(R) Xeon system running Linux is: </p> <blockquote> <p> 2038-Jan-19 03:14:08 -2147483648 </p> </blockquote> <p> We have found that changing the v_type definition from boost::int32_t to typename frac_sec_type::int_type resolves the issue by associating v_type with its implementation's definition. </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/9489 Trac 1.4.3 mreissne@… Thu, 12 Dec 2013 19:31:19 GMT https://svn.boost.org/trac10/ticket/9489 https://svn.boost.org/trac10/ticket/9489 <ul> <li><strong>attachment</strong> → <span class="trac-field-new">boost-posix-date-time-overflow.cpp</span> </li> </ul> <p> Test program to reproduce the error </p> Ticket maxim.yegorushkin@… Fri, 20 Dec 2013 11:38:30 GMT https://svn.boost.org/trac10/ticket/9489 https://svn.boost.org/trac10/ticket/9489 <ul> <li><strong>attachment</strong> → <span class="trac-field-new">date_time_ticket_9489.patch</span> </li> </ul> <p> A patch, as proposed by the ticket author. </p> Ticket Georg Sauthoff <mail@…> Sun, 19 Jan 2014 19:13:54 GMT https://svn.boost.org/trac10/ticket/9489#comment:2 https://svn.boost.org/trac10/ticket/9489#comment:2 <ul> <li><strong>cc</strong> <span class="trac-author">mail@…</span> added </li> </ul> Ticket James E.
