How to properly analyze grossly incoherent colloquial constructs?

Question

Take a question like: > War jetzt morgen eigentlich Probe? The grammatical temporal cues are grossly incoherent: *War* is past tense, *jetzt* points to the present, *morgen* points to the future. No German speaker will have a problem understanding the question, however, because while the sentence is constructed from incoherent temporal cues, they are associated with different semantic layers of perception. Is there a proper way to reflect this when analyzing the question?

Answer 1

"War jetzt morgen eigentlich Probe?"

Erinn dich 'morgen' hat zwei Bedeutungen.

This sounds like "just this morning was the test/examen?"
