Imagine an alarm clock that beeps every 2.5 minutes starting at midnight, that is at 00:00:00, 00:02:30, 00:05:00, 00:07:30 and so on. In six eclipse experiments over eight years in distant locations, some instruments essentially based on test masses exhibited strange behavior only at the exact occurrence of beeps, sometimes simultaneously in distant sites. In the figure there is the trace I recorded during the solar eclipse of May 31, 2003, using a stationary pendulum that was displaced West-East and then back only at times exactly proportional to 2.5 minutes (2m30s). Note: in the graph the vertical grid is spaced 7.5 minute instead of 2.5, for clarity.
