I found an approximate offset time!

I visited the Freescale Discussion forums. People with working chips were sharing where they started and their offset times. A woman who started in the general area that I was in had an offset of about 9 minutes. Based on that, my chip time would be 5:37:53. A personal record. My goal was 5:30:00. I came close.

The back of my right knee and upper calf is still sore.
