Ticket Duration with SLA

[GiHe]

Hello,

New to the OTRS Solution, i would like to know if it's possible to obtain the duration of a ticket taking into account the SLA.
By example, a ticket opened a friday at 10 AM, my SLA is Monday to Friday, 7 AM to 7 PM, and if i close the ticket on Monday 9 AM, the call duration of the ticket is about 11 hours.

Where can i find a such extension / information / help to integrate / parameter a such fonctionnality ?

thanks in advance ,

Cordially,

GiHe
