Why should it? Adverbs and time stamps appear invariably (with the sole exceptions of {neH} and {jay'}) at the beginning of clauses. If you're reading a sentence and you run into a time stamp or an adverb that isn't {neH} or {jay'}, then you already
know you've reached a new clause, in just the same way as you know you've reached a new clause when you hit {'e'}.
One could probably concoct an example of a construction where a noun phrase is ambiguously acting as either a subject of the subordinated clause or as a time stamp of the {'e'}-clause, but I imagine examples where genuine ambiguity arises would be
very few and far between.
