This week the International Earth Rotation and Reference System Service announced they will add a leap second to Coordinated Universal Time (UTC) on June 30, 2015 at 23:59:60 UTC. Qualys has completed our assessment of the Qualys Cloud Platform and its sensors (scanners), and we do not expect any impact or adverse effect.
The International Earth Rotation and Reference System Service (IERS) is a worldwide organization based in Paris, France that observes the Earth’s rotation irregularities and compares it to atomic time. When the difference between the Earth rotation and atomic time becomes greater than 0.9 seconds, they order a leap second to be added worldwide. Since 1972 a total of 25 leap seconds have been added, and the one scheduled for June 30, 2015 is the 26th.
