Time zone messed up?

It would seem that performing IIC bus probing on the Pi causes some strange effects, such as the configuration freezing and being unable to be changed.
What other IIC buses are present on the Pi? I’m getting results (but gibberish) for device 116 on buses 2, 4, and 6 which is weird given that the HAL appears to return an error code for any bus other than zero…?

(ignore this)
