"At what time?"

Translation: A che ora?

[MABBY]

Should "a cosa tempo" also be acceptable?
Strictly speaking, the answer translates as "at what hour".

I want to say "Tempo" refers to the concept of time rather than like a specific time, Which "Ora" can refer to, But I may be wrong.

Wouldn't "A quale ora" make more sense, Since there's only a limited number of times, And you're asking which one?
