The user manual describes how to log time, how to plan time on task and sub-task level and how to work with your timesheet.
Please note that ictime has a very flexible permission management, so that there is no fixed definition of the permissions a user or an administrator has. There are no defined roles for user and administrator, permissions. In general, a typical user should have the permission to log time, plan time on task/sub-task level and to manage their own timesheet. Some users might have the permission to approve work logs. An administrator should have the permission to configure ictime, to use the Reporting & Analysis features and to plan time on project or component level.
