Yes, that may be a better term.  I guess we didn't choose that because
we aren't native English speakers, and because TimeSeries was already
using the other term.

I think that what Francesc was trying to say is that taking holidays
into account would be way too difficult to be implemented.  Timezones
were just an example of another (unrelated) feature we left out due to
