-<p>The Boost Chrono library provides an implementation of the C++0x Standard
-Library's new time utilities and compile-time rational arithmetic. The
-implementation will work with most C++03 conforming compilers.</p>
+<p>The Boost Chrono library provides:</p>
+<ul>
+ <li> The C++0x Standard Library's time utilities, including:<ul>
+ <li>Class template duration</li>
+ <li>Class template time_point</li>
+ <li>Clocks:<ul>
+ <li><code>system_clock</code></li>
+ <li><code>monotonic_clock</code></li>
+ <li><code>high_resolution_clock</code><br>

+ </li>
+ </ul>
+ </li>
+ <li> The C++0x Standard Library's compile-time rational arithmetic.</li>
+</ul>
+
+<p>The implementation will eventually work with most C++03 conforming compilers.
+Initial tests have been run on Windows with VC++ 9.0 SP1 and Intel 11.0, and on
+Ubuntu Linux with GCC 4.2.4.</p>
+
+<h2><a name="Getting-started">Getting started</a></h2>
+
+<p>If all you want to do is to time a program's execution:</p>
+
+<blockquote>
+ <pre>#include <boost/chrono/process_times.hpp>
+
+...
+
+// add this in the scope you want to time,
+// at the point you want the timer to start.
+boost::chrono::run_timer rt;</pre>
+</blockquote>
+<p>Here is a complete program (run_timer_example.cpp):</p>
+<blockquote>
+ <pre>#include <boost/chrono/process_times.hpp>
+#include <cmath>
+
+int main()
+{
+ boost::chrono::run_timer t;
+
+ for ( long i = 0; i < 10000000; ++i )
+ std::sqrt( 123.456L ); // burn some time
+
+ return 0;
+}</pre>
+</blockquote>
+<p>Debug build output was:</p>
+<blockquote>
+ <pre>real 0.832s, cpu 0.813s (97.7%), user 0.813s, system 0.000s</pre>
+</blockquote>
+<p>In other words, the program took 0.832 real-time (i.e. wall clock) seconds to
+execute, while the operating system (Windows in this case) charged 0.813 seconds
+of CPU time to the user and 0 seconds to the system. The total CPU time reported
+was 0.813 seconds, and that represented utilization of 97.7% of the real-time
+seconds.</p>
+<h2><a name="Caveat">Caveat</a> emptor</h2>
+<p>The underlying clocks provided by operating systems are subject to many
+seemingly arbitrary policies and implementation irregularities. That's a polite
+way of saying they tend to be flakey, and each operating system or even each
+clock has its own cruel and unusual forms of flakiness. Don't bet the farm on
+their accuracy, unless you have become deeply familiar with exactly what the
+specific operating system is guaranteeing, which is often very little.</p>
+<h2>FAQ</h2>
+<p><b>Why does run_timer only display millisecond place precision when the
+underlying timer has nanosecond precision?</b> To avoid giving the
+impression of precision where none exists. See Caveat emptor.
+You can always specify additional decimal places if you want to live
+dangerously.</p>
+<p><b>Why does run_timer sometimes report more cpu seconds than real seconds?</b>
+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.</p>

-<h2><a name="Introduction">Introduction</a></h2>
-<p>Knowing how long a program takes to execute is useful in both test and
-production environments. It is also helpful if such timing information is broken down
-into real (wall clock) time, CPU time spent by the user, and CPU time spent by the
-operating system servicing user requests.</p>
-<p>The Boost Chrono Library's process times components provide that information:</p>
-<ul>
- <li>At the highest level, class <code>run_timer</code> provides a
- complete run time reporting package that can be invoked in a single line of
- code.<br>
- </li>
- <li>At a middle level, class <code>process_timer</code> provides a process timer useful
- when the automatic reporting of <code>run_timer</code> isn't desired.<br>
- </li>
- <li>At the lowest level, <code>process_clock</code> provides a
- thin wrapper around the operating system's process timer API. For POSIX-like
- systems, that's the <code>times()</code> function, while for Windows, it's the
- <code>GetProcessTimes()</code> function.</li>
-</ul>
-
-<h2><a name="Example">Example</a>s</h2>
-
-<p>Here is the run_timer_example.cpp
-program supplied with the Boost System library:</p>
-<blockquote>
- <pre>#include <boost/chrono/run_timer.hpp>
-#include <cmath>
-
-int main()
-{
- boost::chrono::run_timer t;
-
- for ( long i = 0; i < 10000000; ++i )
- std::sqrt( 123.456L ); // burn some time
-
- return 0;
-}</pre>
-</blockquote>
-<p><b><span style="background-color: #FFFF00">Warning: The remainder of this
-page is totally out-of-date</span></b></p>
-<p>When the <code>run_timer t</code> object is created, it starts timing. When
-it is destroyed at the end of the program, its destructor stops the timer and
-displays timing information on cout.</p>
-<p>The output of this program run on a circa 2006 processor looks was this:</p>
-<p><code> wall 0.42 s, user 0.41 s + system 0.00 s = total cpu 0.41 s,
-(96.3%)</code></p>
-<p>In other words, this program ran in 0.42 seconds as would be measured by a
-clock on the wall, the operating system charged it for 0.41 seconds of user CPU
-time and 0 seconds of system CPU time, the total of these two was 0.41, and that
-represented 96.3 percent of the wall clock time.</p>
-
-<p>The run_timer_example2.cpp
-program is the same, except that it supplies additional constructor arguments
-from the command line:</p>
-<blockquote>
- <pre>#include <boost/system/timer.hpp>
-#include <cmath>
-
-int main( int argc, char * argv[] )
-{
- const char * format = argc > 1 ? argv[1] : "%t cpu seconds\n";
- int places = argc > 2 ? std::atoi( argv[2] ) : 2;
-
- boost::system::run_timer t( format, places );
-
- for ( long i = 0; i < 10000000; ++i )
- std::sqrt( 123.456L ); // burn some time
-
- return 0;
-}</pre>
-</blockquote>
-<p>Here is the output for this program for several sets of command line
-arguments:</p>
-<blockquote>
- <pre>run_timer_example2
-0.42 cpu seconds
-
-run_timer_example2 "%w wall clock seconds\n"
-0.41 wall clock seconds
-
-run_timer_example2 "%w wall clock seconds\n" 6
-0.421875 wall clock seconds
-
-run_timer_example2 "%t total CPU seconds\n" 3
-0.422 total CPU seconds</pre>

-<h3>Typedef <a name="microsecond_t"><code>microsecond_t</code></a></h3>
-
-<p>The typedef <code>microsecond_t</code> provides an implementation defined type capable
-of representing microseconds. For POSIX and Windows systems, <code>
-microseconds_t</code> is <code>boost::int_least64_</code>t.</p>
-
-<p>The underlying type is not based on the Boost Date-Time library to avoid a
-dependency on a large library. This design choice may change at some future
-date.</p>
-
-<p>Although <code>microsecond_t</code> is capable of representing .000001
-second, the actual resolution of common operating system timers is often only
-.015 second.</p>
-
-<h3>Struct <a name="times_t"><code>times_t</code></a></h3>
-
-<p>The struct <code>times_t</code> packages three elapsed times:</p>
-
-<ul>
- <li>Wall clock elapsed time, equivalent to the time that would be recorded by
- a stopwatch.</li>
- <li>User central processing unit (CPU) time used by the process, as charged by
- the operating system.</li>
- <li>System central processing unit (CPU) time used by the process, as charged
- by the operating system.</li>
-</ul>
-
-<h3><a name="Non-member-functions">Non-member functions</a></h3>
-
-<p>These low-level functions are thin wrappers around the operating system's API
-process timing function, such as POSIX <code>times()</code> or <code>Windows
-GetProcessTimes()</code>.</p>
-
-<p><code>void times( times_t & result );</code></p>
-
-<blockquote>
-
-<p><i>Effects:</i> Stores wall-clock, process user CPU, and process system CPU times,
-as reported by the operating system's API process timing function, in r<code>esult</code>.</p>
-
-<p><i>Throws:</i> <code>boost::system::system::error</code> if the underlying
-operating system API call reports an error.</p>

-
-</blockquote>
-
-<h3>Class <code><a name="timer">timer</a></code></h3>
-
-<p>A <code>timer</code> object measures wall-clock elapsed time, process elapsed
-time charged to the user, and process elapsed time charged to the system.</p>
-
-<p>Unless otherwise specified, all member functions report errors by throwing <code>system_error</code>
-exceptions. If an error occurs and an exception is not thrown, errors are
-reported by setting time values to -1.</p>
-
-<p>The semantics of member functions are achieved by calling the <code>
-times()</code> function.</p>
-

-
-<p><i>Remarks:</i> Member functions for this object will not throw exceptions.</p>
-
-<p><i>Note: </i>On popular operating systems, such as POSIX and Windows, the question of how to handle errors is moot
-since timer errors do no occur. For programs which may
-run on systems that may possibly report timer errors, the <code>nothrow</code>
-constructor allows suppression of exceptions without the interface thickening
-that would be required if all functions had <code>error_code</code> returning
-variations. In the rare cases where exceptions are undesirable yet the <code>
-error_code</code> must be captured, the non-member <code>times</code>
-function's overload returning an <code>error_code</code> can be used.</p>
