The latest dependency report shows chrono as having a dependency on math.

See http://www.pdimov.com/tmp/report-develop-3b5a9f4/module-overview.html

math is really big. In testing bpm, an install of timer (which depends
on chrono) slowed noticeably when it got to math. Presumably the build
is also much slower, although I haven't tested that yet.

Is the math dependency really needed?

Thanks,
