All master time is set the same as in any club. How do you set the wind up clocks so they all are the same setting over the whole combine or Federation? Some of you are grabbing at stars here. This is the new and modern world. We have atomic clocks that all read the same and are set from the same satellite so they all read the same, this is also the way we set our club units. Each club decides what unit they will use, if a flyer wants another kind of clock it is his job to supply the club unit and leave it at the club. Each clock company has a diffrent program for just there clocks.
