How to generate a full report in redmine?

Question

Redmine

Currently, the work reports in Redmine are generated after the task is solved and the participant has indicated the number of hours for the solution. The program displays this number of hours in the report. It is necessary that the time of labor costs begin to be calculated immediately after the creation of the task until the moment the task is solved.
For example, if the task was created at 8:00 and solved at 12:00, where the participant solved it for 2 hours, but the report indicated 4 hours. Since the time is taken into account immediately after the creation of the task.
