I have a page type in the admin with a date field. When I enter a date in the admin for example September 8, 1994 it displays correctly in the front end but when i refresh the admin the date displays as Septemeber 8, 1993 one year behind. Any suggestions as to why this is happening?

ArticlePage.php

<?php

class ArticlePage extends Page {
	static $db = array(
		'Date' => 'Date',
		'Time' => 'Time'
	);
	
	static $has_one = array('ArticleAuthor' => 'Author');
	
	static $has_many = array('ArticleImages' => 'ArticleImage');
	
	function getCMSFields() {
		$fields = parent::getCMSFields();
		
		$fields->addFieldToTab('Root.Content.Main', $dateField = new DateField('Date','Article Date (for example: 12/12/2011)'), 'Content');
    		$dateField->setConfig('showcalendar', true);
		    $dateField->setConfig('dateformat', 'MM/dd/YYYY');
	   $fields->addFieldToTab('Root.Content.Main', $timeField = new TimeField('Time','Article Time (for example: 00:00:00)'), 'Content');
		    $timeField->setConfig('showdropdown', true);
		
		$articleimages = new ImageDataObjectManager(
			$this,
			'ArticleImages',
			'ArticleImage',
			'Image',
			array(
				'Name' => 'Name',
				'Caption' => 'Caption'
			),
			'getCMSFields_forPopup'
		);
		$fields->addFieldToTab('Root.Content.ArticleImages', new LiteralField('Article Images Break', '<br />'));
		$fields->addFieldToTab('Root.Content.ArticleImages', new LabelField('Article Images Label', 'Article Images'));
		$fields->addFieldToTab('Root.Content.ArticleImages', $articleimages);
		
		$author = new HasOneDataObjectManager(
			$this,
			'ArticleAuthor',
			'Author',
			array(
				'FirstName' => 'FirstName',
				'MiddleName' => 'MiddleName',
				'LastName' => 'LastName',
				'Link' => 'Link'
			),
			'getCMSFields_forPopup'
		);
		$fields->addFieldToTab('Root.Content.Author', new LiteralField('Article Author Break', '<br />'));
		$fields->addFieldToTab('Root.Content.Author', new LabelField('Article Author', 'Article Author'));
		$fields->addFieldToTab('Root.Content.Author', $author);
		
		return $fields;
	}
}

Hello.

I got the same strange behavior. Did you get this problem solved?

I don't know if this is the same thing but I remember running into something like that once, where it helped using yyyy instead of YYYY. I can still reproduce it - but in my case only for the first of januari :-)
