ZF-12023: Zend_Feed_Writer_Feed does not accept UNIX timestamps which are not 10 digits
There are 3 methods in Zend_Feed_Writer_Feed_FeedAbstract which try to build a Zend_Date object by timestamp. The problem lies within the recognition of the timestamp value. There is a disputable presumption about the proper length of a timestamp string. Only strings which are 10 characters long (and containing only digits) are considered to be an timestamp. That leads to problems with dates before 2001-09-10 because their timestamps only have the string length of 9 characters.
The methods are:
setDateCreated() setDateModified() setLastBuildDate()
