NAME
Date::Extract::P800Picture - extract the date from Sony Ericsson P800 pictures
VERSION
This document describes Date::Extract::P800Picture version v1.1.4.
SYNOPSIS
use Date::Extract::P800Picture;
$filename = "8B360001.JPG"; # 2008-12-04T6:00:00
$parser = new Date::Extract::P800Picture();
$parser = new Date::Extract::P800Picture('filename' => $filename);
$datetime = $parser->extract();
$datetime = $parser->extract($filename);DESCRIPTION
The Sony Ericsson P800 camera phone stores pictures taken with the camera on the device with a filename consisting of the date and the hour the picture was taken, followed by a four digit number and the .JPG extension. The format of the date and the hour is YMDH, in which the single characters are base 36 to fit a range of about 36 years, 12 months, 31 days and 24 hours since the year 2000 in a case insensitive US-ASCII representation.
SUBROUTINES/METHODS
- Date::Extract::P800Picture->new()
- Date::Extract::P800Picture->new('filename' => $filename)
-

- $parser->filename($filename);
-
Sets the filename to extract the date and hour from.
- $obj->extract()

DEPENDENCIES
INCOMPATIBILITIES
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.
For perls earlier than 5.14 version 0.04 of this module provides the same functionality in a perl 5.6 compatible way.
DIAGNOSTICS
An exception in the form of an Exception::Class named DateExtractP800PictureException is thrown when a date can't be extracted from the string:
No date found in filename '%s'
Filename is not set, nothing to extract
BUGS AND LIMITATIONS
Usually the files are transferred from the P800 to other systems in a way that hasn't 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.
There are no error values to provide different exit statuses for different failure reasons
