Awaiting service

This is not an evening blip.  I noticed the clock was showing the wrong time as I went to ring the bells. The tower clock specialist is coming this week to service it.  I don't touch tower clocks especially as this one has a synchronous motor rather than a mechanical movement.  The first time I touched it I managed to set the hands rotating backwards!.  I should like to be able to do that with my own body clock.
