Daylight Savings Time Inanity
the time again for the inane practice of "springing ahead" by one hour
on our clocks. This biannual hour time shift is a minor inconvenience
to the world's timekeepers compared to adding occasional leap days and
most annoyingly, leap seconds. In 1967, by international agreement,
the second was defined as the duration of 9,192,631,770 transition periods
of the cesium-133 atom. Earth's orbital period is not consistent from
year to year due to erratic perturbations of the other planets and tidal
effects of the moon that are slowing the rotational period of the earth.
This causes leap seconds to be added at irregular intervals to maintain
agreement with the atomic clocks, which can cause real problems when
synchronizing aviation, stock market, scientific, astronomical and many
other timing systems. Since leap seconds were first implemented in 1972,
22 seconds have been added. Estimates say the Earth has lost 3 hours
total in the last 2000 years. Maybe this explains why my work days seem
longer any more.
