Displays the date and time a change was made. The column also includes email address of the person who initiated the change in the account. For example,
May 21, 2016, 1:26:17 PM
An email address is shown for changes made by using the user interface, a bulksheet or bulk operations, and scheduled edits. If an automated system such as sync made the change, the user section of the column is empty.
You can use the column to sort the list of changes. You can also filter the change history report by the user email addresses shown in this column.
