60, 00. This is the only type of leap second that has occurred so far (note the +1’s in the table). Negative leap seconds: A second is removed, so the seconds on a UTC clock might read 57, 58 SYSTEM\CurrentControlSet\Control\LeapSecondInformation • For pre-2018 leap seconds, we maintain a static constexpr table to pull data from. • Note that we don’t currently have a way to detect upcoming leap seconds October update). • However, because leap seconds happen infrequently, we plan to update this static table periodically so older OSes can still detect more recent leap seconds (they will just need to update
