I am looking for few of these options if there is any way to implement in OS ticket

1. Timings & Holiday calender

Is there any method to define the support timings and holiday calender in Os ticket.

There should be provision to calculate the ticket overdue time as per official hours.

2. There should be report (GUI) available to know from which end user/ customer - most tickets was generated and same with the Help Tpoics

3. Time calculation per ticket

Any method where support staff can click when he actually stated working on the ticket and when it was closed, to know the actual hours spent on ticket

Regards
