Strange date time issues in customer view

[seansan]

Whilst thinking to fix a small error I ran into several strange issues occuring in customer edit view in adminthtml (customer/edit). Several things are unexpected. Let me explain

• Local Time now is May 9 4:32 PM (UTC Now = May 9 3:32)
• Local Timezone Amsterdam/Netherlands
• Local Account creation date is July 27 2015 at 8:38 AM

Below are some strange things

1. The last login date is very strange. Year is incorrect. Time is minutes off.
2. The account creation date is not 7:38 AM it was 8:38 AM (i have also jus confirmed this by creating a new account. Even stranger , the order datetime is 4:32 PM but the account creation datetime - which occured at the same time - shows as 3:32 PM)

So there seem to be 2 problems

1. getLastLoginDate / logindate date does not seem correct
   (however the localized LastLoginStore is! correct)
2. but the same date getter for getStoreCreateDate is not! correct and is 1 hour off (here I would expect 2 lines als showing the alternative localized version)

I hope it is a little clear

Possible solution for 1.

• formatdate() in Mage_Core_Helper_Data has a check for instanceof zend_date but the date passed in getLastLoginDate() in Mage_Adminhtml_Block_Customer_Edit_Tab_View is a member of Mage_Core_Helper_Data and thus returns false
• As a result strtotime is performed on the date object here
• A possible fix is to add the following to getLastLoginDate() here

        $date = $this->getCustomerLog()->getLoginAtTimestamp();
        if ($date) {
        $date = new Zend_Date($date, Zend_Date::TIMESTAMP);

I discovered this issue today in OpenMage 20.0.7 instance in production. A fix should be implemented.
