Yes, indeed. Anyway, after looking at the overall picture, I don't think
it's such a good idea after all.
This is because of time_duration, since users might then expect .days()
to be there, which could even break some existing code.

Yes, indeed. But using fixed-point decimals ;-)

Eventually you could do something like:

hours( one_day() );

or something similar.

I'll be back with more requests ;-)
