The expanding Universe

The expanding Universe Just became a paid member, the guilt from listening for so long for free was to much ! You do a fantastic job of bringing us a truly top rate podcast. My question - on large scales the Universe is expanding by increasing the amount of Space where, whatever force is causing the Universe to expand, that force is greater than gravity. Hope that makes sense ! However, if Space itself is expanding (and Time is bound up with Space to be SpaceTime), does this mean that on those large cosmic scales Time is also being created along with Space ? In other words the very fabric of Space is being created.. ?? Or is the existing fabric of space being stretched and what does that mean for the Time part of that Space that is being stretched ? Would Time run slower in that stretched Space ?
