Aj,
Contemplating your clock slow running problem (in my tent at the weekend), I'd be inclined to have a look at the connection between the printed circuit strip and the pins that feed volts to the clock, they're riveted connections that can become intermittent.
Also, you could remove the clock from the cluster and feed 12v directly to the input sockets to see if it looses time. That would isolate the fault to either the clock or the wiring.
Good luck,
Paul.
