The announcement to insert a leap second is usually issued whenever the difference between UTC and UT1 approaches 0.7s, to keep the difference between UTC and UT1 from exceeding ±0.9 s. After UTC 23:59:59, a positive leap second at 23:59:60 would be counted, before the clock indicates 00:00:00 of the next day. Negative leap seconds are also possible should the Earth's rotation become slightly f ...

The Second Epistle of Peter is a book of the New Testament of the Bible. The opening verse identifies itself as having been written by Simeon Peter, who has been identified with Saint Peter, although nowhere else in the New Testament is he referred to as both Simeon (the Aramaic form of Simon) and Peter. It has been considered by some as evidence that Peter himself wrote the text rather than an amanuensis (as with the previous epistle). This understanding is also used to argue against a pseudepigraphal author in light of the unlikelihood of a late writer attempting to feign an ori ...

The Second Book of Enoch (usually abbreviated 2 Enoch, and otherwise variously known as Slavonic Enoch or The Secrets of Enoch) is a Jewish pseudepigraphic apocalyptic text of uncertain date and unknown authorship. It is unrelated to the Book of Enoch; the numbering of these texts has been applied by scholars to distinguish the texts from one another. The text has been preserved only in Slavonic, but this has certainly been translated from Greek. It is widely held that the Greek version may itself have been a tran ...

The factor of 60 comes from the Babylonians who used factors of 60 in their counting system. The hour had previously been defined by the ancient Egyptians in terms of the rotation of the Earth as 1/24 of a solar day. This made the second 1/86,400 of a solar day. With the development of clocks keeping mean time (as opposed to the apparent time displayed by sundials), the second became 1/86,400 of a mean solar day. In 1956 the second was defined in terms of the period of revolution of the Earth around the Sun for a particu ...

Leap seconds are necessary because time is measured utilizing stable atomic clocks (TAI or International Atomic Time), whereas the rotation of the Earth has been slowing down. Traditionally, the second has been defined as 1/86400 of a mean solar day (see solar time). This is determined by the rotation of the Earth around its axis and its orbit around the Sun; time was measured by astronomical observations. However, the solar day has gradually become 1.7 ms longer every ...
