Therefore, when necessary a "leap second" is applied to UTC. +# Since the adoption of this system in 1972 it has been necessary to add a number of seconds to UTC, +# firstly due to the initial choice of the value of the second (1/86400 mean solar day of +# the year 1820) and secondly to the general slowing down of the Earth's rotation. It is +# theoretically possible to have a negative leap second (a second removed from UTC), but so far, +# all leap seconds have been positive (a second has been added to UTC). Based on what we know about +# the earth's rotation, it is unlikely that we will ever have a negative leap second. +# +# +# HISTORY +# The first leap second was added on June 30, 1972. Until the year 2000, it was necessary in average to add a +# leap second at a rate of 1 to 2 years.
