It was Only a Matter of Time
In this timely presentation by Dr Leon Lobo from the National Physical Laboratory (NPL), we found out that it is definitely not a short-term nor a trivial matter. The technical issues that have been overcome through the years and the refinements now under development are mind boggling. NPL are always striving for greater accuracy and stability: They are currently developing Strontium ion optical clocks amongst others. Why couldn't we just have stayed using the sun, the moon and the stars, as had been done since the time of the Pharaohs? Well, nobody wants to miss their train and with London and Bristol differing by 11 minutes, it's tough to run a railway timetable if the time is uncertain.
