Yes. The problem is rather simple. If you have
in usage requirements of "foo" then usage requirements of date_time will be
applied only to targets that use "foo". The "foo" target will be built as
usual. To achieve the effect you want, it's necessary to and
to *requirements* section as well. That would signify that your library uses
date_time library and usage requirement will be propagated.
I've wrote a document which describe all this some time ago, but it never
ended in docs :-(
