This amendment adds another TLV to the Announce messages, containing details of the latest Leap-second event specified by the International Earth Rotation and Reference Systems Service (IERS). The fields comprise the date of the latest event, plus the total accumulated seconds offset after the event. The TLV will also indicate for how long the latest event information may be considered valid (so clocks in holdover may continue to provide UTC time for more than 12 hours after loss of a time source).
