Hmmm.  I seem to have missed that part.

However, for better portability (and higher boost usage points), I can
use date_time.  The test program, using date_time is attached.

I agree, but I am still a Boost.Build/Boost.Test neophite.  The jamfile
is simple enough, but what is *not* there is what makes it confusing for
us old "make" hacks...
