Hi everyone

**Case:**  
I have a backend service that need to deliver high performance response times during business hours, but outside business hours also is&nbsp;(knowingly and accepted) impacted by batch activity&nbsp;🤠&nbsp;I want a Service Level Objective for the service, but only have it evaluate data within business hours.

**Question:**  
Is it possible to set the&nbsp;Service Level Objtective timeframe expressions for fixed business hours only? I have tried a few things with the example expressions, but can not get it to work. The SLO is based on custom metrics, but I dont find an option to set at time limit here either.

Lets say I want my Service Level Objective to evaluate the last week, but only between 9am to 5pm?

Best regards

Rasmus
