[boost] Lag of trunk tests?

I'm watching the trunk regression summary for several days and almost all the tests are reportedly stale at 19-21 August. If I go, for instance, to <http://www.boost.org/development/tests/trunk/Sandia-sun.html> it says that tests are run *nightly* (incidentally, it also doesn't tell anything about the gcc invocation). What's wrong? -- Genny
