Oops, I meant: yes please make stopwatches a sublibrary of chrono and then see if it needs to set off on its own.

All I want is a replacement for boost::timer, for writing benchmarks.  I never used the progress_timer so I don't know about the reporting side of Boost.Timer, never wanted it.  I want a simple class that keeps track of elapsed time so I don't have to even do one subtraction.

In one quick pass of the Stopwatches documentation, I can't find anything that doesn't do automatic reporting.  I figure there must be a class in there that looks a lot like boost::timer or the one in Chrono's "key is struck" example, which is what your original question must be proposing.

I find Boost.Timer kind of buggy.  It was reporting CPU time on Linux, so I couldn't benchmark a parallelized program.  I feel it has other problems.  I thought Chrono was supposed to replace it, but it's still a little verbose for this very simple task.

Cheers,
