RE: [Boost-users] date_time clocks, microsec_clock, etc
For those that need something portable we should be able to get microsecond resolution for Windows, Linux, and probably a few more...

Microsecond resolution on linux? What interface provides this? I have a linux platform or 2 that I'm pretty sure won't provide it at present, but probably could with some kernel hacking, if only there was some sensible interface to connect it to user space.

The way to do this would be with the newer POSIX clock_gettime() etc. Its only well-implemented in recent Linux kernels supposedly, and I have not yet tested it myself. I notice some other systems seem to be using clock_gettime() also. rdtsc might be a possibility too for Intel machines if uncertainties with it could be worked out. Aaron

Sorry, I was thinking that ACE was able to get microsec resolution on Linux, but it appears I was mixing it up with Solaris. BTW, this page might be a useful reference: http://www.dre.vanderbilt.edu/Doxygen/Current/html/ace/classACE__High__Res__... Jeff BTW -- this discussion should really move to the dev list...
