Leap Seconds have been added since 1972.
Fortunately most dedicated NTP servers are designed with Leap Seconds in mind.
Leap seconds are added or subtracted as necessary to keep UTC in sync with the Earth's rotation.
The adjustment in our time is known as leap seconds which are added either once or twice a year to UTC.
Leap seconds are a point of controversy, but without them, the day would slowly drift into night(albeit after many centuries);
These incremental changes are known as Leap seconds and are identified in the signals sent to most NTP servers.
Whilst Google's solution to the Leap Second is ingenious,for most computer systems Leap Seconds cause no problems at all.
So far, 24 of these‘Leap Seconds' have been since 1972 when UTC first became the international timescale.
Based on both TAI and GMT,UTC allows for the slowing of the Earth's rotation by adding leap seconds every year or two and sometimes twice a year.
Leap Seconds can also cause problems if networks are synchronised using Internet time sources or devices that require manual intervention.
UTC is adjusted by the insertion of extra seconds, called leap seconds, as necessary to keep it within a second of GMT or UT1.
The time code contains the year, day of year, hour, minute, second, and flags that indicate the status of Daylight Saving Time,leap years, and leap seconds.
Leap Seconds were introduced to compensate for the unpredictability of the Earth's rotation and to keep UTC(Coordinated Universal Time) with GMT Greenwich Meantime.
UTC is based on the time told byatomic clocks although compensation measures such as Leap Seconds are added to UTC to keep it inline with Greenwich Meantime GMT.
Leap Seconds prevent the actual time as told by atomic clocks and the physical time, governed by the sun being highest at noon, from drifting apart.
Next year, however, a group of astronomical scientists and engineers,plan to draw attention to the forced nature of Leap Seconds at the World Radiocommunication Conference.
Normally leap seconds are added to the very last minute of December 31 but occasionally if more than one is required in a year then is added in the summer.
The time code contains the year, day, hour, minute, second, and as it is a source of UTC, any leap seconds that are added to ensure parity with the rotation of the Earth.
Not everybody is happy with leap seconds, there are those that feel that adding of seconds to keep the Earth's rotation and UTC inline is nothing but a fudge.
It is based on the traditional 24-hour Earth rotation known as Greenwich Meantime(GMT)but accounts for the inaccuracies in the earth's spin by having so-called‘Leap Seconds' added or subtracted.
Leap seconds are required to measure two sources of time- one which uses the vibration of atoms, which is known as Coordinated Universal Time(UTC) and one which uses the Earth's rotational spin UT1.
UTC is used by NTP time servers(Network Time Protocol)as a time reference to synchronise computer networks and other technology and the disruption Leap seconds can cause is seen as not worth the hassle.
Leap seconds are normally inserted once or twice a year(normally on New Year's Eve and in June) to ensure the global timescale UTC(Coordinated Universal Time) coincides with the astronomical day.
UTC also compensates for the slowing of the Earth's spin by adding leap seconds to ensure there is no drift that would eventually cause noon to drift towards night albeit in many millennia;
NTP Time Servers ensure that all networked computers are synchronized automatically to the accurate time and date, now and in the future,automatically updating the network during daylight saving and leap seconds.
With a computer network synchronised with an NTP server, Leap Seconds are adjusted automatically at the end of a day and occur only rarely, so most computer systems never notice this small hiccup in time.
If nothing was done to compensate for this,eventually noon would become midnight and vice versa(albeit in many millennia) so leap seconds are added to the standard time scale just as days are added in a leap year.
Some suggest to combat this problem leap seconds should be eliminated and the world should stick with just atomic time even though that would result in sun at midnight and dark during the day albeit in 43,000 years time.
Strictly speaking GPS time differs from the international timescale UTC(coordinated Universal Time)as UTC has had additional leap seconds added to it to ensure parity with the earth's rotation meaning it is exactly 18 seconds ahead of GPS but is easily converted by NTP the time synchronisation protocol Network Time Protocol.
UTC accounts for the slowing of the Earths rotation by adding leap seconds to TAI so as to prevent the gradual drift of night into day(although that would take 40,000 years or so) and allows the whole world to communicate using the same timescale.
