OK, since your timestamps are all a mess you have 2 choices...
1. Assume that all files on one system are correct and rsync --archive
from it to the other. Rsync will go through all the data but it will
only actually transfer the differences. It will take time but less
time than actually re-copying everything.
2. Same as the above but add --size-only to rsync. This will tell
rsync to assume that files that are the same size on both systems are
actually the same. Usually files that are the same size actually are
the same but obviously that isn't a guarantee so this can create cases
of old data with new dates.
- From now on always copy timestamps!
