Why?
When I serviced electromechanical time clocks in factories
years ago, it was not unusual to find serious misalignment
problems in brand new clocks that had been installed straight
out of the box. It dawned on me later that the company I
worked for may have imported them untested as part of a
reduced-price deal.
