I have a really big problem since I live at an altitude of 1100 meters. Thanks to relativity, time goes much quicker for me then all you lowlanders - about 1 part in 10-13 times faster.
So do I set my clock to keep in sync with sea level clocks, which means my clock is actually running slow, or do I set it correctly which means my clock will always be gaining time on the sea level clocks. If I set my local clock deliberately slow, then the error filters through to everything else that is time related, like the measurement of capacitance. I hate buying a 1nF capacitor from Jaycar, only to find that when I measure it at home, it only reads as 0.99999999999987 nF.
