Pétùr, don't get crazy about FS corruption. There is no sign this is the case so far. Date and UID's are odd, but valid within ext4. Remove the immutable flag (chattr -i), you will be able to alter the files as you like.
One hint will be, check if your system time is ok (both, date and hwclock!), may be there is a reason for this odd timestamps.
