Remember to turn your clocks ahead one hour at 2 a.m. Sunday March 8 as we move to daylight time.
Because our official time is kept with atomic clocks that are accurate to about one second in 20 million years, but the rotation of the earth is gradually slowing down, scientists will add a “leap second” when needed to adjust the astronomical time (earth’s rotation) to the atomic time.
The next leap second will be added at 23:59:60 UTC on June 30, or for B.C. residents, at 4:59:57 pm June 30.
Scientists are expected to vote this year on whether to eliminate leap seconds and just rely on atomic time only.
