If time contraction at the periphery is say 0.01% (and I have no idea whether that is the right figure, probably nowhere near) and at the centre is 100 times this because the density is also 100x, then time dilation at the centre would be 1%. Hence time at the centre would run at about 99% that of the periphery.
or
That time contraction may be 100 times greater but time would not be running 100 times faster. Are you questioning the numeric relationship between time contraction and time passing faster.
Just because time dilation is 100 times greater does not necessarily mean time runs 100 times slower. It might, but not necessarily and probably not in the case of the Milky Way, whose density is very low anyway.
