In 1849 the church clock and the old clock from the Shambles differed by about 20 or 30 minutes. This was because Mr. John Horton, who looked after the church clock, adjusted it to the time according to the old coaching days, whilst James Conneybear, in charge of the Shambles clock, set it to the new countrywide railway time. This in spite, said the Western Times, 'of the non-commencement of the Ashburton Railway.'
