There is a problem with this definition, in that UTC did not exist in its current form until 1972 this issue is discussed below. The Unix epoch is the time 00:00:00 UTC on 1 January 1970. Interpreter programs can then convert it to a human-readable format. Unix time is a single signed number that increments every second, which makes it easier for computers to store and manipulate than conventional date systems. Some of the examples also show International Atomic Time (TAI), another time scheme which uses the same seconds and is displayed in the same format as UTC, but in which every day is exactly 86 400 seconds long, gradually losing synchronization with the Earth's rotation at a rate of roughly one second per year. The second layer encodes that number as a sequence of bits or decimal digits.ДЄs is standard with UTC, this article labels days using the Gregorian calendar, and counts times within each day in hours, minutes, and seconds. The first layer encodes a point in time as a scalar real number which represents the number of seconds that have passed since 00:00:00 UTC Thursday, 1 January 1970. Two layers of encoding make up Unix time. 1.2.1 Non-synchronous Network Time Protocol-based variant.In Unix-like operating systems, date is a command which will print or set the current time by default, it prints or sets the time in the system time zone, but with the -u flag, it prints or sets the time in UTC and, with the TZ environment variable set to refer to a particular time zone, prints or sets the time in that time zone. Unix time is widely used in operating systems and file formats. Due to this treatment of leap seconds, Unix time is not a true representation of UTC. Unix time is nonlinear with a leap second having the same Unix time as the second before it (or after it, implementation dependent), so that every day is treated as if it contains exactly 86 400 seconds, with no seconds added to or subtracted from the day as a result of positive or negative leap seconds. The Unix epoch is 00:00:00 UTC on 1 January 1970 (an arbitrary date). It is the number of seconds that have elapsed since the Unix epoch, excluding leap seconds. Unix time (also known as Epoch time, Posix time, seconds since the Epoch, or UNIX Epoch time ) is a system for describing a point in time. It was celebrated in Copenhagen, Denmark at a party held by DKUUG (at 03:46:40 local time). Unix time passed 1 000 000 000 seconds on.
