> The clock was recently overhauled, and is acting as the master clock again. For years, the hotel's time signals were coming from an electric motor clock and then a quartz time standard. But they've reverted to the pendulum clock. Error is about 5 seconds a month.

Can't anyone donate them a retired Cesium clock? Or, at least, a GPS receiver.

no no no, you are misreading causality here. The error of 5 seconds a month is between the One True Clock (the one with the pendulum) and all those silly cessium and gps dohickies.
