=head1 CONFIGURATION AND ENVIRONMENT

No configuration and environment settings are used.

=head1 DEPENDENCIES

=over 4

=item * perl 5.14 

=item * L<POSIX|POSIX>

=item * L<English|English>

=item * L<DateTime|DateTime>

=item * L<Readonly|Readonly>

=head1 INCOMPATIBILITIES

=over 4

=item * To avoid ambiguity between more common date notations and the
Sony Ericsson P800's date notation this is a separate module. It's highly
unlikely that in any other setting "2000" means the first of January 2002.

=item * For perls earlier than 5.14 version 0.04 of this module provides the
same functionality in a perl 5.6 compatible way.

=back

=head1 DIAGNOSTICS

An exception in the form of an L<Exception::Class|Exception::Class> named
C<DateExtractP800PictureException> is thrown when a date can not be extracted
from the string:

=over 4

=item * No date found in filename '%s'

=item * Filename is not set, nothing to extract

=back

=head1 BUGS AND LIMITATIONS

=over 4

=item * The date could be from another timezone, based on the device settings
and when and where the picture was taken.

=item * Usually the files are transferred from the P800 to other systems in a
way that has not completely preserved the timestamp of the file, so there is
no reliable way to double check the results by comparing the date extracted
from the filename with the timestamp of the file.

=item * There are no error values to provide different exit statuses for
different failure reasons
