fix for ISO date format and changes related to data requirment @ front

Fixed date format to ISO. There is big gotcha in java.util.Date and it does not inter operate easily with real ISO format hence JODA is used. However JODA too work annoyingly if you input it a util date partly because util date does not have time zone. At the moment is application assumed that date has format yyyyMMdd as string and then convert in ISO using JODA lib.

Also updated data to satisfy various front end requirements
