Suppose I write: {loSmaH wa' ben jIboghpu'} for "I am 41 years old".

Literally though, the klingon goes "41 years ago I have been born"
i.e. 41 years ago my "being born" has been completed.

Lets forget this for the moment..

If I write {wa'Hu' pItSa' vISoppu'}, this means that "one day ago my
eating the pizza has been completed". But I could have eaten this
pizza many days ago, and yesterday is just another day during which my
eating of the pizza continues to be completed.

I remember someone asked Okrand about something similar to this, and he replied that using {-pu'} with a time-stamp adverbial implies that the completion occured at the time of the time stamp. Sadly, I am having trouble finding the exact canon for this at the moment.
