Absolute Time?

    If time slows down near a massive body like the Earth, is that actually the slowing down of time our is it just the slowing down of light?

    "Light moves at the exact same speed in all reference frames."

    ^ Central tenet of relativity

    Our clocks run more slowly. Interestingly, this must be accounted for in GPS satellites to properly "synchronize" their clocks with our ground-based ones.

    So time actually does slow down, and it doesn't just seem like it's slowing down.
