Our measurement techniques and assumptions lead us to believe that 13+
odd billion years has elapsed, but what if we are wrong? According
to relativity, immense mass concentration slows down the rate of time
passage and it is difficult to imagine a more dense concentration than
that of the initial big bang mass of the entire known
universe.
At Multiverse Impasse, a New Theory of Scale

Mass and length may not be fundamental properties of nature,
according to new ideas bubbling out of the multiverse.
(I'm not sure if that article
addresses time, which may also be -- in the way WE experience it --
emergent. At the lowest level it might just be a "click" from
one state to another. At present the clicks are so regular that we see
them as a smooth flow. At some earlier configuration a billion of
"our" years could pass between clicks.)
