/*!
 * \brief A class of an attribute that makes an attribute value of the time interval since construction
 *
 * The timer attribute calculates the time passed since its construction and returns it on value acquisition.
 * The attribute value type is <tt>boost::posix_time::time_duration</tt>.
 *
 * On Windows platform there are two implementations of the attribute. The default one is more precise but
 * a bit slower. This version uses <tt>QueryPerformanceFrequence</tt>/<tt>QueryPerformanceCounter</tt> API
 * to calculate elapsed time.
 *
 * There are known problems with these functions when used with some CPUs, notably AMD Athlon with
 * Cool'n'Quiet technology enabled. See the following links for more information and possible resolutions:
 *
 * http://support.microsoft.com/?scid=kb;en-us;895980
 * http://support.microsoft.com/?id=896256
 *
 * In case if none of these solutions apply, you are free to define <tt>BOOST_LOG_NO_QUERY_PERFORMANCE_COUNTER</tt> macro to
 * fall back to another implementation based on Boost.DateTime.
