However I’m trying to relate it to service response. Our helpdesk is open from 730AM till 630PM. So I find myself trying to calculate the difference between e.g.
01/12/2010 09:00 and 02/12/2010 10:00 which using a time diff command is 25hrs 0 mins. However I need to remove 11 hours from that as those hours are out of SLA, similarly I need to so the same for calls spanning a weekend. I have around 6000 calculations to make so an automated formula would be a huge help. Any advice would be greatly appreciated
