2^128 ~= 3.4 x 10^38 [0]
Age of the universe in seconds ~= 4.3 x 10^17 [1]
So assuming you're using an unsigned int to represent the number of seconds from the big bang, you'll still have ~ 10^21 seconds left on the clock (31.7 trillion years).
Unless you're working with a timeline that extends out to the heat death of the universe (10^100 -> 10^(10^56) years), 128 bits should be enough.
