Are Red Hat Ceph Storage Clusters affected by the upcoming leap second inclusion on December 31 2016?

Solution In Progress - Updated -


  • Due to the differences in the earth's rotation speeds due to various geographical factors, Earth's time, also called Solar time, tend to change.

  • Atomic clocks maintain the UTC (Coordinated Universal Time) standard which is used across the globe as a basis for civil time.

  • Since the Atomic clocks progress at a steady state which does not change, it goes out of sync with the Solar time.

  • To bring the Atomic clocks in sync with the Solar time, changes are introduced in UTC time in the form of leap seconds.

  • A leap second essentially pulls back the Atomic clocks and hence UTC by that much, which puts it in sync with the Solar time.

  • A leap second insertion is coming up on December 31st, 2016.
