POM provides a system attribute (addedOn) that displays the time when a new contact was imported, uploaded, or added into a contact list. This attribute is a part of all contact lists for all organizations. The value of the addedOn attribute for all the contacts imported earlier to POM 4.0.2 Service Pack 3 will be set to the time of upgrade to version 4.0.2 Service Pack 3.
With this attribute, a user can filter contacts based on their age. For example, if a user wants to filter contacts added before 30 days, the user can use this attribute to filter the records.
