Hi all,<br /><br />I have the following little program (I&#39;m using mingw 3.4.2 (32bit) ):<br /><br />#include &lt;boost/date_time/posix_time/posix_time.hpp&gt;<br />#include &lt;iostream&gt;<br /><br />int main()<br />{<br />  using namespace boost;<br />  using namespace boost::posix_time;<br /><br />  //Time now (since epoch in seconds)...<br />  static const ptime secSinceEpoch( second_clock::local_time() );<br /><br />  //Time now (since epoch in micros)...<br />  static const ptime microsecSinceEpoch( microsec_clock::local_time() );<br /><br />  //Elapsed should be close to zero...<br />  time_duration elapsed = microsecSinceEpoch - secSinceEpoch;<br />  <br />  std::cout &lt;&lt; &quot;elapsed: &quot; &lt;&lt; elapsed.total_milliseconds() &lt;&lt; std::endl;<br />  return 0;<br />}<br /><br />It outputs:  &quot;elapsed: -1240428644900&quot;, whereas I expected it to<br />output a positive value.<br /><br />It therefore seems that microsec_clock::local_time() wraps. Is 64-bits <br />a pre-requisite for this library to work correctly or is there some remedy?<br /><br />Kind regards,<br /><br />Werner
