Leap Second queries related to tzdata

Solution Verified - Updated -

Issue

  • As per the Red Hat Leap Second Article, I need to update the tzdata package. Do I need to take any further actions after updating tzdata?

  • If my RHEL host is a NTP client, do I need to update the tzdata package? What if I do not update the tzdata package OR I just only update the ntp package and the kernel as per the Red Hat Leap Second Article?

  • Is it necessary to have the latest tzdata package for avoiding any issues during the addition of leap second?

  • For my RHEL host which is not a NTP client what will happen if I do not update the tzdata package?

  • What are the TAI and the UTC time scales? Do I need to consider these time scales while upgrading the tzdata package?

  • For my RHEL host which is not a NTP client and using the TAI timescale, should I be upgrading the tzdata package?
