I had the same error with
tar (GNU tar) 1.13.93
amanda version 2.4.4p3
kernel 2.4.24
Rest of restore was fine, files were ok, so I didn't investigate too
much ;-)

 For some reason, tar thinks the file's timestamp is 0, or else
 the timestamp recorded in the tarball is in fact 0.  (1969-12-31
 17:00:00 is the UNIX epoch, converted to your local timezone.)
 I'm not sure why it's happening.
 
 Are you sure you're using GNU tar for both the backup and the
 restore?  If the backup used gtar but the restore used your
 vendor's tar, there might be an incompatibility.

I've seen the same message when restoring on a different machine than the
backup was taken. Both backup and restore machine had GNU tar, but different
versions (restore machine is an Athlon XP running current Debian testing,
backup machine is an Alpha running a very old Debian version (the one before
woody (slink?), I think)). Didn't notice any other problems, but I didn't do a
full restore anyway, I just had to look at some files in /etc.

If anyone is interested in more details, I can look up the version of GNU tar
in the backups (old machine itself is stored in mottballs right now).

Which version of gtar are you using?  Some versions are known to
be incompatible with Amanda; I haven't seen this particular
problem before, but it's a possibility to consider.  1.13.25 is
the usually recommended version for use with Amanda.  Darn, I
keep forgetting whether anyone has seen problems with 1.14 or
not.  Sorry. :-(

Just out of curiosity, what does stat say about the *restored*
file?
