Hello folks,<br><br>Today I downloaded the new version of Boost, 1.38, and tried to compile and run the <a class="link" href="http://www.boost.org/doc/libs/1_38_0/doc/html/boost_asio/tutorial/tuttimer5/src.html" title="Source listing for Timer.5">Source listing
        for Timer.5</a> example from Asio, but it was throwing the exception:<br><br>&quot;could not convert calendar time to UTC time&quot;<br><br>(Note that i&#39;m building it under windows vista using MinGW GCC,
which I believe is not on the &quot;tested compilers list of boost 1.38&quot;)<br><br>After some time traking the culprit, I got to the function <br>time_type microsec_clock::create_time(time_converter converter) from the boost\date_time\microsec_time_clock.hpp header<br>
in which the variable &#39;std::time_t t&#39; was strangely assuming a negative value, probably due to an overflow.<br><br>Then I realized that changing the type of the variable &#39;micros&#39; from uint64_t to std::time_t on that same function, could solve the problem.<br>
<br>I just want to know if that&#39;s a known issue and if applying that small fix other issues may appear.<br><br>Thanks in advance<br>Bruno<br>
