As it seems there is already an open bug regarding this package 
The patch that is posted there ports binclock to python 3 however the maintainer
hasn't responded as of yet. So the porting work has already been done basically, as a
downstream patch at least, only the changes need to be pushed by the maintainer. However
the best way, I think, would be to contact upstream about python 3 support.
