Hey @SakshiBagal 

Whenever we set the system property com.snc.time_worked.update_task_timer to true, the Time Worked field on the Incident form is being reset to 0 each time it is updated.
The data is being entered correctly into the Time Worked table (task_time_worked) so that it exists; however, the Incident form is not calculating the total from this table. 

The "Update task timer" Business Rule had been customized, and this customization is causing the undesired results., Your solution could be revert the OOTB BR to its initial state

I hope my repsonse helps !

Regards

Sumit
