Trying to create Service Area drive times from speed limits with Network Analyst

I want to create a service area map using Network Analyst. I have the ESRI Street feature class set up in a Network Dataset, but I cannot figure out how to display the driving time polygons. I can only get it to display by distance (like 1000 meters from the facility). The Street feature class has speed limits listed for each street segment, but no time attributes. I assumed that the Network Analyst could calculate time from the speed automatically, but I cannot figure out how to get the extension to do this. Any pointers?
