NTP Leap Bits

These graphs show the fraction of servers advertising various NTP leap second bits around the times of year that leap seconds can be introduced. Leap 01 means add a second, leap 10 means remove a second, leap 00 means no leap second is yet expected and leap 11 means the server is currently unsynchronised. The line at the middle of each graph shows the point at which a leap second could be introduced.
