And I told you that the function is supposed to give you that, unless
there is none.
If the time period you specified (also see below) only has unknown data,
then what can be returned apart from nan?

You ALWAYS specify a time period. If you omit the parameters, you rely on
the defaults, which may not be what you want/need.
