- Subject: Tar fails when tarball contains an old file
I'm running cygwin 1.5.5-1 on win2k and finally figured out that when
attempting to untar a tarball containing a file with a timestamp of
1/1/1970, it fails - in this case, killing cpan:
tar: libwww-perl-5.76/README: Cannot utime: Invalid argument
This makes sense since window's epoch is 1/1/1980, making it impossible to
accurately transcript the true (though perhaps bogus) modification date. I
presume that all dates prior to 1980 would be problematic. Seems to me that
tar should do the best it can by setting the timestamp to 1/1/1980 and issue
a warning, but not fail.
I'm new to the group and searched the archives, but not seen this issue
addressed. And I'm not sure if this is really a bug in tar, but the *nix
folks won't ever encounter this problem.
