Version 2 of Boost.Timer is about ready to move to trunk. The original version 1 timers are deprecated, but not changed in any way. Besides deciding to keep the version 2 timers in Boost.Timer, many suggestions and corrections from the "Boost.Timer replacement" thread have been applied. See http://lists.boost.org/Archives/boost/2011/09/185820.php The docs can be viewed at http://beman.github.com/timer/ The code is available at https://github.com/Beman/timer Thanks to all who posted comments, corrections, and suggestions in response to the original posting. Special thanks to Rob Stewart - many of his suggestions have been incorporated - and to Vicente Botet for his work on Boost.Chrono which now is used to implement much higher resolution for wall-clock time. While additional comments are always welcome, unless someone comes up with a showstopper I'm planning to move Version 2 to trunk and get on with other projects. --Beman
