Ian,

Although on average LOD is more than 86400 s by a few milliseconds, in the past fifty years about 3% of the days have been shorter than 86400 s. In the past decade alone the figure is 14% (the earth has sped up quite a bit the past decade). You can imagine then that some days must be rather close to no error.

Five days were within 1 microsecond and the record goes to November 29, 2004 which was just 200 nanoseconds shy of a perfect 86400 second day.
