I want to make what I hope is not an offensive inquiry. As a native (American) English speaker, both of your uses of the word "since" look wrong to me. In my reading, the first one should be "for" and the second should be "until". This is not the first time I've come across jarring uses of "since" online. What I'm wondering is: What is your background? Are you also a native English speaker from a different region? If so, what region? If not, what is your native language and is the English "since" deceptively similar to a word in it? To try to make it less likely that this comment makes you feel bad, I will close by making the (true) statement that I found your comment to be interesting and insightful and your usages of "since" didn't hurt my comprehension at all, they just sounded weird.
