+This code was derived by Beman Dawes from Howard Hinnant's time2_demo prototype.
+Many thanks to Howard for making his code available under the Boost license.
+The original code was modified to conform to Boost conventions and to section
+20.9 Time utilities [time] of the C++ committee's working paper N2798.
+See http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2798.pdf.

+time2_demo contained this comment:

+ Peter Dimov,
+ Jeff Garland,

+
+TODO:
+
+ * Fully implement error handling, with test cases.
+ * Use boost::throw_exception. (Currently not used because of an issue with Intel 11.0.)
+ * Consider issues raised by Michael Marcin:
+
+ > In the past I've seen QueryPerformanceCounter give incorrect results,
+ > especially with SpeedStep processors on laptops. This was many years ago and
+ > might have been fixed by service packs and drivers.
+ >
+ > Typically you check the results of QPC against GetTickCount to see if the
+ > results are reasonable.

+ >
+ > I've also heard of problems with QueryPerformanceCounter in multi-processor
+ > systems.
+ >
+ > I know some people SetThreadAffinityMask to 1 for the current thread call
+ > their QueryPerformance* functions then restore SetThreadAffinityMask. This
+ > seems horrible to me because it forces your program to jump to another
+ > physical processor if it isn't already on cpu0 but they claim it worked well
+ > in practice because they called the timing functions infrequently.

+ > In the past I have chosen to use timeGetTime with timeBeginPeriod(1) for
