Created, Created by, Updated, and Updated by

These fields are quite similar, but are used too frequently that we'd be remiss not to discuss them.

The Created [sys_created_on] field contains the date and time of the creation of this task record.

The Created by [sys_created_by] field tells you who created the record.

Updated [sys_updated_on] and Updated by [sys_updated_by] are the same as their corresponding Created fields, except that they are continually updated as the record is updated, to show when the most recent update was, and who made it. These fields can be exceptionally useful for reporting and determining who's working on what tickets, and whether any tickets are slipping through the cracks.
