Peter Clare, a local clockmaker, made a clock for Manchester Corporation.
From 1848, this was the official clock for Manchester, showing the current time as measured at the Royal Observatory in Greenwich.
At first, astronomy was used to regulate the clock to Greenwich Time. After 1852, the Royal Observatory transmitted the time hourly by telegraph. The clock stood in the Town Hall on King Street where people could use it to set the time on their own watches and clocks. Greenwich Mean Time was not adopted as the national standard time until 1880. The clock was moved to the Manchester Blackpool Art Gallery in 1912.
