Okay. So I've read the documentation back to front but I'm utterly confused with the SLA timing...

INFO:
Our internal Service Desk has the following operational hours: Monday-Friday 09:00-18:00 (9 working hours per day)
We have the following SLA's



QUESTIONS:
Q1. If I set a 1 working day response/resolution does SD+ take into account our working day is made up of 9 hours and not 24?

I want to ensure that a request raised on a Friday at 14:00 doesn't reach the 1 working day SLA until Monday at 14:00 and not Saturday at 14:00

Q2. If we have a SLA with a response of 1 day and want to alert the ticket owner (technician) two hours before the SLA is about to be violated do I set the escalation as:

Escalate before: / 2 hours / 0 minutes???

Thanks
