Media::DateTime - An highly extensible module to extract the creation date and time from a file.
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 );
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.
Constructor that returns a
Media::DateTime object. Methods can be called on either the class or an instance.
my $dt = Media::DateTime->new;
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 the excellent
DateTime module which simplifies the handling of dates. See
Module::Pluggable::Ordered which are used to implement the plugin system.
Image::Info is used to extract data from JPEG files for the
Make sure you have configured the local time zone on your machine. See
DateTime::TimeZone::Local for information on how the timezone is determined.
