Time may or may not be infinite, but that's probably a philosophical or a mathematical question that I am not competent enough to answer. There are different theories on this, but I don't think that anyone knows for sure which is the case. I've also come across a lecture on Perimeter Institute in which a physicist argues that time may not even exist (i.e that it's just an illusion). The idea of a timeless reality can also be traced back to Plato and many other philosophers of the past.
Secondly, yes, there may exist other universes which have their own "time bubble" and those universes might even have a different set of physical laws than that of the universe that we are aware of. There could be billions of other universes each having a different set of laws and a different time bubble. Where is the end point in all of that? Obviously, nobody knows.
From a theistic stance, however, we believe that God is the end point, but God Himself has no end point (which sounds like a paradox, apparently). God created time and space and thus He is beyond them. This means that God is a timeless reality. All created things exist in time and space, while God is 'outside' of them and/or not limited by them.
