create service area based on actual time values in CF output

I've performed a closest facility(CF) problem, so that I have a time value representing the travel time between a selected set of block group points and their nearest facility.

Now, I'd like to create service areas around each facility point that take into account the actual time value from the field in my CF output of block groups to the same nearest facility.  I'd like my service area break points to be 30 60 90 minutes. 

How would I go about doing this? 

The concept is similar to creating discrete contour surfaces with a set of points based on their values in relation to another point (their nearest facility). I'm interested in skipping Python at this time, if we can.
Thank you.
