In no time meaning: very fast, not “never”

In no time means very quickly: we'll be there in no time. But change one preposition, and the phrase stops praising speed and swears something never happened.

In no time means very quickly: with two people helping, we packed the boxes in no time. About the future, it means very soon: the station is nearby, we'll be there in no time. For extra emphasis, say in no time at all. It sounds casual and upbeat.
