Work-in-progress for the Boost.Chrono library has been added to the sandbox. See http://svn.boost.org/svn/boost/sandbox/chrono
This work is in a very preliminary state. The only testing has been with VC++ 9.0 on XP-64 and a tiny bit on Ubuntu 8.04 Linux. There has been no work done yet on C++0x headers. The Jamfiles are there, but haven't been tested; I've been developing using the provided VC++ solution.
The implementation of the clocks is going to be very system specific. If anyone would like to try .../libs/chrono/example/await_keystroke.cpp and report whether or not it compiles and works on their system, it would be appreciated. Patches to make .../libs/chrono/src/chrono.cpp work for various operating systems would be even more appreciated!
I'm still unsure about even some of the basics, such as how to partition the three parts for boost. Are the time utilities, the compile-time rational arithmetic, and the type trait common_type three boost libraries, one boost library, or three parts of a larger boost library? There was some discussion of this in a prior thread, but I thought having the actual code available might move the discussion forward.
There is a tiny bit of documentation; see .../libs/chrono/doc/index.html.
Comments welcome!

Hi Beman, I've tried the ../libs/chrono/example/await_keystroke.cpp with VC++ 9.0 (SP1) on a XP-32 system in release and debug mode. It seems to work very well. Output at debug mode: Strike any key: abc system_clock-----------: 2.359420300 seconds monotonic_clock--------: 2.360545544 seconds high_resolution_clock--: 2.361268541 seconds system_clock latency-----------: 0 monotonic_clock latency--------: 2235 high_resolution_clock latency--: 1956 system_clock::now() reports UTC is Wed Nov 12 16:02:54 2008 Output at release mode: Strike any key: abc system_clock-----------: 2.734427500 seconds monotonic_clock--------: 2.742866761 seconds high_resolution_clock--: 2.743364311 seconds system_clock latency-----------: 0 monotonic_clock latency--------: 1676 high_resolution_clock latency--: 1676 system_clock::now() reports UTC is Wed Nov 12 16:04:17 2008 Franz
