Cortana music controls offline?

[mildor]

Using an iphone 4 (cause I have no option T_T )
I want to buy lumia 830

There are ANY question cortana can answer offline? Such as saying what time is it or control music
I heard that she can't, and it was a bit surprising because even iphone 4 voice commands can do that simple tasks

Ya she can control your music and make calls in offline
