Eureka wrote:[So does that mean that, in Greek, words that pinpoint the time of the verb's action (i.e. yesterday, earlier, etc) are not used in sentences that have a verb of the perfect tense?
The same way we wouldn't say "I have fed the cat yesterday." *
I'd think time adverbs would match the tense of the perfect form. So, words that make sense with the present tense are probably fine with the present perfect ("I shut now," vs. "I have shut the door now") , and those with the past would go with the past perfect ("I had shut the door on the Ides of March."), or the (rarely used) future perfect, ("I will have shut the door tomorrow").
But I'll have to go digging into some Greek texts to verify all of this. However, since there are a number of perfects used commonly to express things we'd use the present for ("to know" [face=spionic]oi)=da[/face] comes to mind), I suspect what I said above is correct for Greek and English both.
