if the area is sufficiently deep as to have significant dilation, it's sufficiently deep that people will be turned to jam.

The difference between 0.9G and 1G is measured in centiseconds per year. And a year is roughly 31536000 seconds.

To have livable for humans, the G's can't exceed 2 by much... and that's still only going to be no more than single digit seconds per year.

you're not going to get humans surviving significant gravitational dilation without having significant centrifugal pseudo-force... but that's got other issues, as well, since the gravitational gradient over 2m with significant time dilation is going to be enough that your speed won't save you from spaghettification.
