Hi Lamby. Perfect, I will check the GitHub code instead of Debian
Sources. I was thinking tar archives are normalised by
strip-nondeterminism based on the next contents:

B<strip-nondeterminism> is a tool to strip bits of nondeterministic
information, such as timestamps, from files.  It can be used as
a post-processing step to make a build reproducible, when the build
process itself cannot be made deterministic.

=item B<-T> I<seconds>, B<--timestamp> I<seconds>

Instead of stripping timestamps from files, set them to the given number
of seconds since January 1, 1970.

=item B<--clamp-timestamp>

Only replace timestamps if they are later than the time specified to
B<--timestamp>.  You can use this option to ensure that only timestamps
introduced as part of the build process are replaced.  NOT YET IMPLEMENTED
FOR ALL FILE FORMATS.

my $cmd = $0;
$cmd =~ s/.*\///;
my $usage
  = "Usage: $cmd [-v|--verbose] [-t|--type FILETYPE] [-T|--timestamp
SECONDS] [--clamp-timestamp] FILENAME\n";

my ($filetype, $timestamp, $clamp_timestamp, $want_help, $verbose,
$want_version);
my $getopt = Getopt::Long::Parser->new;
$getopt->configure(qw(no_ignore_case permute bundling));
$getopt->getoptions(
	'type|t=s', \$filetype,
	'timestamp|T=i', \$timestamp,
	'clamp-timestamp!', \$clamp_timestamp,
	'help|h', \$want_help,
	'verbose|v', \$verbose,
	'version|V', \$want_version
) or die $usage;

$File::StripNondeterminism::canonical_time = $timestamp;
$File::StripNondeterminism::clamp_time = $clamp_timestamp;

print "$cmd: Not using a canonical time\n"
  if not defined $timestamp and $verbose;
for my $filename (@ARGV) {
	die "$filename: Does not exist\n" unless -e $filename;
