It is very necessary to check for registration of the spent time with the date of the task that does not fall into the date.
The check "IF THE DATE OF SPENT TIME DOES NOT FALL WITHIN THE TASK START AND END RANGE, THEN BAN AND WARNING", which could be selected in the settings, would be very helpful to control users with a large pool of tasks.
For example, a task starts on 10/01/2020 and ends on 10/12/2020. And the user registers in the task a record of the spent time with the date 10/13/2020. The system should issue a warning "The date of spent time 10/13/2020 is not included in the task date range 10/01/2020 - 10/12/2020!" and forbid the user from saving a record of the spent time.
