[SR-Users] Issue in cdr generation in seconds format

Hello Sir, I need your expertise for kamailio cdr generation in seconds format. I have a requirement to generate cdr duration in second format.Now I am getting second.milliseconds format.Below is the log where duration is 18.676 but I want this to be 19.(suppose where duration =18.234, I need it to be 18).
