note syphilis <i>I have a Grandfather clock that ticks once every 2 seconds, (and tocks every two on the alternate second). But it also looses around 30 minutes a day.</i><br><br>Nothing wrong with the clock ... it's just that time itself now runs faster than it did when the clock was built ;-)<br><br>You could compensate for this by shortening the periodicity of the pendulum ?<br><br>Cheers,<br>Rob 1000994 1000999
