greenwich obseratory Shepherd master clock This master clock was installed at the Royal Observatory after the Great Exhibition in 1851. From 1852 to 1893 it was the UK's master timekeeper, and the heart of the world's first time distribution network sending time signals around the UK. It drove slave dials around the Royal Observatory including the large dial outside the gates, the first clock to show Greenwich Time directly to the public. Lund synchronised clock The Royal Observatory was the ultimate, but not the only, supplier of accurate time to the UK. Subscribers to the Standard Time & Telephone Company leased clocks like this, automatically corrected by an hourly electrical signal. On receiving the signal, a pair of pins at the top of the dial snap together, pulling the minute hand to exactly zero. GPS relies on extremely accurate atomic timekeeping to calculate positions, and an error of just 1/100 second could put the calculation 3000km out. In GPS satellite atomic clocks, nanoseconds really matter.

So, after a hard night at college i was left puzzled by a question that someone asked and that no-one could answer...so..... If all time is set to GMT, and we have to change or clocks to suit it in winter/summer etc...Who/ where is the main clock that tells the exact time????? One friend said it was a clock in the swis alps on a moutain so no-one could tamper with it and another said it was Big Ben, LMAO!!! So, where is the main clock that tells the world what time it is???? LOU XXXXXXXXXXX

don't know where the main clock is but what if it becomes faulty how will we know the correct time then? Jackiexx
