/**
* @brief Returns the last modified time of the record.
*
* @return long Unix timestamp marking the last time the record was modified.
*
* @since 0.8
*
* @section Synopsis
*
* This method will first check to see if the delegate class implements a method
* named getLastModified() and return its result. If none can be found it will
* attempt to guess which field is used to store the last modified date
* (based on the Dataface_Table::getLastUpdatedField() method). Otherwise it will
* simply return 0.
*
* This method is used throughout Xataface to mark the modification times of records.
*
