* A type for representing points in time: __time_point__. A __time_point__ represents an epoch plus or minus a __duration__. The library leaves epochs unspecified. A __time_point__ is associated with a /clock/.
* Several clocks, some of which may not be available on a particular platform: __system_clock__, __monotonic_clock__ and __high_resolution_clock__. A clock is a pairing of a __time_point__ and __duration__, and a function which returns a __time_point__ representing ['now].

minutes m4 = m3 + us3;
It won't compile. The rationale is that implicit truncation error should not be allowed to happen. If this were to compile, then `m4` would hold `5`, the same value as `m3`. The value associated with `us3` has been effectively ignored. This is similar to the problem of assigning a double to an `int`: the fractional part gets silently discarded.

+[section But what if the truncation behavior is what I want to do?]
There is a __duration_cast__ facility to explicitly ask for this behavior:
- minutes m4 = __duration_cast__<minutes>(m3 + us3); // m4.count() == 5
+ minutes m4 = bchrono::__duration_cast__<minutes>(m3 + us3); // m4.count() == 5
In general, one can perform __duration__ arithmetic at will. If __duration_cast__ isn't used, and it compiles, the arithmetic is exact. Any place one wants to override this exact arithmetic behavior, __duration_cast__ can be used to explicitly specify that desire. The __duration_cast__ has the same efficiency as the implicit conversion, and will even be exact as often as it can.
+You can use __duration_cast__`<>` to convert the __duration__ into whatever units you desire. This facility will round down (truncate) if an exact conversion is not possible. For example:
+
+ bchrono::__nanoseconds__ start;
+ bchrono::__nanoseconds__ end;
+ typedef bchrono::__milliseconds__ ms;
+ ms d = bchrono::__duration_cast__<ms>(end - start);
+
+ // d now holds the number of milliseconds from start to end.
+
+ std::cout << ms.count() << "ms\n";
+
+We can convert to __nanoseconds__, or some integral-based duration which __nanoseconds__ will always exactly convert to, then __duration_cast__`<>` is unnecessary:
+
+ typedef bchrono::__nanoseconds__ ns;
+ ns d = end - start;
+ std::cout << ns.count() << "ns\n";
+
+If you need seconds with a floating point representation you can also eliminate the __duration_cast__`<>`:
+
+ typedef bchrono::__duration__<double> sec; // seconds, stored with a double
+ sec d = end - start;
+ std::cout << sec.count() << "s\n";
+
+If you're not sure if you need __duration_cast__`<>` or not, feel free to try it without. If the conversion is exact, or if the destination has a floating point representation, it will compile: else it will not compile.
+
+
+If you need to use __duration_cast__`<>`, but want to round up, instead of down when the conversion is inexact, here is a handy little helper function to do so. Writing it is actually a good starter project for understanding __Boost_Chrono__:
+
+ template <class ToDuration, class Rep, class Period>
+ ToDuration
+ round_up(bchrono::__duration__<Rep, Period> d)
+ {
+ // first round down
+ ToDuration result = bchrono::__duration_cast__<ToDuration>(d);
+ if (result < d) // comparisons are *always* exact
+ ++result; // increment by one tick period
+ return result;
+ }
+
+ typedef bchrono::__milliseconds__ ms;
+ ms d = round_up<ms>(end - start);
+ // d now holds the number of milliseconds from start to end, rounded up.
+ std::cout << ms.count() << "ms\n";

I don't want to deal with writing `duration_cast` all over the place. I'm content with the precision of my floating point representation
Not a problem. When the destination of a conversion has floating point representation, all conversions are allowed to happen implicitly.
- typedef __duration__<double, __ratio__<60> > dminutes;
+ typedef bchrono::__duration__<double, __ratio__<60> > dminutes;
dminutes dm4 = m3 + us3; // dm4.count() == 5.000000083333333

+[section How Expensive is All of this?]
If you were writing these conversions by hand, you could not make it more efficient. The use of __ratio__ ensures that all conversion constants are simplified as much as possible at compile time. This usually results in the numerator or denominator of the conversion factor simplifying to `1`, and being subsequently ignored in converting the run time values of the tick counts.
[endsect]
-[section How complicated is it to build a function taking a `duration` parameter?]
+[section How Complicated is it to Build a Function Taking a `duration` Parameter?]
There are several options open to the user:
* If the author of the function wants to accept any __duration__, and is willing to work in floating point __duration_s__, he can simply use any floating point __duration__ as the parameter:
- void f(duration<double> d) // accept floating point seconds
+ void f(bchrono::duration<double> d) // accept floating point seconds
{
- // d.count() == 3.e-6 when passed microseconds(3)
+ // d.count() == 3.e-6 when passed bchrono::microseconds(3)
}
- f(microseconds(3));
+ f(bchrono::microseconds(3));
* If the author of the function wants to traffic only in integral __duration_s__, and is content with handling nothing finer than say nanoseconds (just as an example), he can simply specify nanoseconds as the parameter:
- void f(nanoseconds d)
+ void f(bchrono::nanoseconds d)
{
- // d.count() == 3000 when passed microseconds(3)
+ // d.count() == 3000 when passed bchrono::microseconds(3)
}
- f(microseconds(3));
+ f(bchrono::microseconds(3));
In this design, if the client wants to pass in a floating point __duration__, or a __duration__ of finer precision than nanoseconds, then the client is responsible for choosing his own rounding mode in the conversion to nanoseconds.
- __duration__<double> s(1./3); // 1/3 of a second
- f(duration_cast<nanoseconds>(s)); // round towards zero in conversion to nanoseconds
+ bchrono::__duration__<double> s(1./3); // 1/3 of a second
+ f(bchrono::duration_cast<bchrono::nanoseconds>(s)); // round towards zero in conversion to nanoseconds
In the example above, the client of f has chosen "round towards zero" as the desired rounding mode to nanoseconds. If the client has a __duration__ that won't exactly convert to nanoseconds, and fails to choose how the conversion will take place, the compiler will refuse the call:
- f(s); // does not compile
+ f(s); // does not compile
* If the author of the function wants to accept any __duration__, but wants to work with integral representations and wants to control the rounding mode internally, then he can template the function:
- template <class Rep, class Period>
- void f(__duration__<Rep, Period> d)
- {
- // convert d to nanoseconds, rounding up if it is not an exact conversion
- nanoseconds ns = duration_cast<nanoseconds>(d);
- if (ns < d)
- ++ns;
- // ns.count() == 333333334 when passed 1/3 of a floating point second
- }
+ template <class Rep, class Period>
+ void f(bchrono::__duration__<Rep, Period> d)
+ {
+ // convert d to nanoseconds, rounding up if it is not an exact conversion
+ bchrono::nanoseconds ns = bchrono::duration_cast<bchrono::nanoseconds>(d);
+ if (ns < d)
+ ++ns;
+ // ns.count() == 333333334 when passed 1/3 of a floating point second
+ }
- f(__duration__<double>(1./3));
+ f(bchrono::__duration__<double>(1./3));
* If the author in the example does not want to accept floating point based __duration_s__, he can enforce that behavior like so:
- template <class Period>
- void f(__duration__<long long, Period> d)
- {
- // convert d to nanoseconds, rounding up if it is not an exact conversion
- nanoseconds ns = duration_cast<nanoseconds>(d);
- if (ns < d)
- ++ns;
- // ns.count() == 333333334 when passed 333333333333 picoseconds
- }
-
- f(__duration__<long long, pico>(333333333333)); // About 1/3 of a second worth of picoseconds
+ template <class Period>
+ void f(bchrono::__duration__<long long, Period> d)
+ {
+ // convert d to nanoseconds, rounding up if it is not an exact conversion
+ bchrono::nanoseconds ns = bchrono::duration_cast<nanoseconds>(d);
+ if (ns < d)
+ ++ns;
+ // ns.count() == 333333334 when passed 333333333333 picoseconds
+ }
+ // About 1/3 of a second worth of picoseconds
+ f(bchrono::__duration__<long long, boost::pico>(333333333333));
Clients with floating point __duration_s__ who want to use f will now have to convert to an integral __duration__ themselves before passing the result to f.
In summary, the author of f has quite a bit of flexibility and control in the interface he wants to provide his clients with, and easy options for manipulating that __duration__ internal to his function.

The __duration__ template uses the __duration_values__ trait to construct special values of the __duration_s__ representation (`Rep`). This is done because the representation might be a class type with behavior which requires some other implementation to return these special values. In that case, the author of that class type should specialize __duration_values__ to return the indicated values.

-
-The type of `ratio_substract<__ratio__<2,3>,__ratio__<1,3> >` could be `__ratio__<3,9>` so the compilation could fail in (2). It could also be `__ratio__<1,3>` and the compilation succeeds.

-
-The meaning of synonym let think that the result should be a normalized ratio equivalent to `__ratio__<T1, T2>`, but there is not an explicit definition of what synonym means in this context.
-
-If the CopyConstruction and Assignment ([[@http://home.roadrunner.com/~hinnant/issue_review/lwg-active.html#12811281 [*LWG 1281]]) is not added we need a typedef for accessing the normalized ratio, and change 20.4.2 to return only this normalized result. In this case the user will need to

Ask your operating system supplier. The results have been inspected with a debugger, and both for Windows and Linux, that's what the OS appears to be reporting at times.
+
+[heading Are integer overflows in the duration arithmetic detected and reported?]
+
+[*Boost.Ratio] avoids all kind of overflow that could result of arithmetic operation and that can be simplified. The typedefs durations don't detect overflow. You will need a representation that handles with.
+
+[heading What clock should be used to benchmarking?]
+
+Each clock has his own features. It depends on what do you need to benchmark. Most of the time, you could be interested in using a thread clock, but if you need to measure code subject to synchronization a process clock would be better. If you have a multi-process application, a system-wide clock will be needed.
