日历应用程序取值日期（1970年1月1日）默认为前端如果设备语言为英语[香港特别行政区中国]

Calendar app take value date(January 1st, 1970) as default in frontend if device language is english[Hongkong SAR china] in my website based on magento framework.Is there any solution to get current time? and the problem is only in Internet Explorer.

here is the screenshot

Finally the problem is solved. And the code is here, ( It works in all browser because of its constant English[US] time format and it doesn't care about your browser's language.)

before,

 $currentDate = new Zend_Date(Mage::getModel('core/date')->timestamp());

after,

$currentDate = new Zend_Date(Mage::getModel('core/date')->timestamp(),null, "en_US");
