No, I would say that sentence one is stating a general truth, not speaking in a way resembling English historical present tense.
(You can just say wa' DIS as a time expression. We have the example of wa' jaj in TKW that does the same thing. wa' DIS pItSa' chab vISop One year, I ate pizza.)
I really don't think another extended discussion of the difference between using perfective in the past and not using perfective in the past is going to be of any help. Perfective means you're looking back at an action completed no matter where in time that action occurs relative to you. Lacking perfective or continuous suffixes means the sentence means anything other than perfective or continuous.-- SuStel http://trimboli.name
