Interesting information indeed. So lets approach this differently.

Suppose I write {jaj veb, vIghro' tIQ wIHaH'eghmoH}, for "next day we bathe the ancient cat".

The first question is "is this ungrammatical ?", and the second question is "what is the {jaj veb} if not a timestamp ?".

I don't think its ungrammatical, and seemingly/apparently {jaj veb} functions as a timestamp.

The only problem is, we don't know which day this {jaj veb} refers to.

Does anyone disagree ?
