Happy New Year to one and all, The University Clock has gained 0.5 seconds against UTC in the past week but is now 2.0 seconds ahead of UTC because of the leap second. If Frank removed coins in accordance with the LWG for 0.5 seconds, then the clock's rate would be rectified but the clock would still be 2 seconds fast next week. Therefore, Frank should apply a LWG of 2.5 seconds and adjust again when the clock is showing the correct time.
