NAME

Media::DateTime - An highly extensible module to extract the creation date and time from a file.

SYNOPSIS

  use DateTime;
  use Media::DateTime;
  my $dt = Media::DateTime->datetime( $file );
  
  # or more cleanly OO
  my $dater = Media::DateTime->new;
  my $dt = $dater->datetime( $file );

DESCRIPTION

Provides a very simple, but highly extensible method of extracting the creation date and time from a media file (any file really). The base module comes with support for JPEG files that store the creation date in the exif header.

Plugins can be written to support any file format. See the Media::DateTime::JPEG module for an example.

If no plugin is found for a particular file (or the plugin returns a false vale) the file creation date as specified by the O/S is used.

Returns a DateTime object.

METHODs

new

Constructor that returns a Media::DateTime object. Methods can be called on either the class or an instance.

        my $dt = Media::DateTime->new;
datetime

Takes a file as an arguement and returns a DateTime object representing its creation date. Falls back to the creation date specified by the filesystem if no plugin is available.

        my $dt = Media::DateTime->datetime( $file );
        # or
        my $dt = $dater->datetime( $file );

SEE ALSO

See the excellent DateTime module which simplifies the handling of dates. See Module::Pluggable and Module::Pluggable::Ordered which are used to implement the plugin system. Image::Info is used to extract data from JPEG files for the Media::DateTime::JPEG plugin.
