I want to know the answer to the following question:
Even if signed  and ratified on the same date, the treaty might have done what on different dates?
All the background I'm provided with is that "When the text of a treaty is later reprinted, such as in a collection of treaties currently in effect, an editor will often append the dates on which the respective parties ratified the treaty and on which it came into effect for each party.". Is that enough to answer the question?
Answer: yes
