The most accurate measurement known to humanity is the measure-
ment of the duration of the second. The peak of the pyramid for accu-
rate time and frequency is the international reference, UTC. The current
best accuracy for the determination of the second results in a time error
of ±0.3 nanoseconds (billionths of a second) per day. This is equivalent
to ±1 second in 10 million years.

As the article may be somewhat dated the current time error may be even less?
