Dear All,
I hope you all enjoyed the extra second
in bed this morning and that your alarm
clock didn't go off one second early.
Here is an easy question to start off
the New Year...
Every Sunday at 08:00 I check the first
stroke of the hour-bell of the University
Clock against a radio-controlled UTC clock.
If it is slow I add coins to the tray on
the pendulum. If it is fast I remove
coins. My formula for the required
adjustment includes a figure for:
Last Week's Gain [LWG]
Here are my recent observations:
25 December clock 0.5 seconds fast
1 January clock 2.0 seconds fast
Is the appropriate figure for LWG:
a) 0.5 seconds
b) 1.5 seconds
c) 2.5 seconds
