A negative leap second would suppress second 23:59:59 of the last day of a chosen month so that second 23:59:58 of that date would be followed immediately by second 00:00:00 of the following date. Since the introduction of leap seconds, the mean solar day has outpaced atomic time only for very brief periods and has not triggered a negative leap ...
The problem exists in systems which measure Unix time—the number of seconds elapsed since the Unix epoch (00:00:00 UTC on 1 January 1970)—and store it in a signed 32-bit integer. The data type is only capable of representing integers between −(2 31 ) and 2 31 − 1 , meaning the latest time that can be properly encoded is 2 31 − 1 ...
The last leap year we had was in 2020 and there won't be another one until 2028. ... That extra 5 hours 48 minutes and 56 seconds starts to add up and needs to be accounted for somehow. Hence ...
Our last leap year was in 2020, so 2024 is the year we make up that extra time. ... The Julian calendar ended up being 11 minutes and 14 seconds longer than the tropical year — the time it takes ...
When dealing with periods that do not encompass a UTC leap second, the difference between two Unix time numbers is equal to the duration in seconds of the period between the corresponding points in time. This is a common computational technique. However, where leap seconds occur, such calculations give the wrong answer.

It is the basis for Coordinated Universal Time (UTC), which is used for civil timekeeping all over the Earth's surface and which has leap seconds. UTC deviates from TAI by a number of whole seconds. As of 1 January 2017, immediately after the most recent leap second was put into effect, [4] UTC has been exactly 37 seconds behind TAI. The 37 ...
The leap second happens every few years when the standard time around the world is adjusted by one second to account for a slight mismatch between clocks and the earth's rotation. And it has some ...
