If only it did update ctime but I tried it with vfat and ext2 and it
doesn't.
As kernel does not update ctime or mtime, when a directory is moved, it is a
kernel problem not a tar problem.

VFAT Filestore example:
df -k .
Filesystem           1k-blocks      Used Available Use% Mounted on
/dev/hda15                7972      4536      3436  57% /DRVL
mount . -fv
/dev/hda15 on /DRVL type vfat (rw)
stat dir1
  File: "dir1"
