Reasons for that buried in the past I guess, and maybe not too
useful to try to answer - for the second question, GetHour() should
be easy to grep for, and operator- has at least client code in
editeng/source/misc/svxacorr.cxx, sfx2/source/doc/objcont.cxx, and

It's unclear to me, how valuable it is to fix-up tools/time.hxx &
all client code, vs. to use e.g.
http://www.boost.org/doc/libs/1_47_0/doc/html/chrono.html when you
need a sane implementation in new code ...

At the very least, documenting your findings in tools.hxx of course
would be great.
