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 earliest stage that we are confident about is some time before the electroweak symmetry breaking, at a temperature of around 10 15 K, approximately 10 −15 seconds after the Big Bang. The electromagnetic and weak interaction have not yet separated , and the gauge bosons and fermions have not yet gained mass through the Higgs mechanism .

Unix time passed 1 000 000 000 seconds on 2001-09-09T01:46:40Z. [1] It was celebrated in Copenhagen, Denmark, at a party held by the Danish UNIX User Group at 03:46:40 local time.
As many common implementations of the leap year algorithm are incomplete or are simplified, they may erroneously assume 2100 to be a leap year, causing the date to roll over from 28 February 2100 to 29 February 2100, instead of 1 March 2100. The DS3231 hardware RTC has the 2100 year problem, because it uses 2-digit to store the year. [61]
The 1986 short story "The End of the Whole Mess" by Stephen King refers to the Doomsday Clock being set at fifteen seconds before midnight due to elevated geopolitical tension. [ 52 ] The Doomsday Clock was a recurring visual theme in Alan Moore and Dave Gibbons 's seminal Watchmen graphic novel series (1986–87), its 2009 film adaptation ...
3.16 Rs (1 × 10 20 a): The estimated time until all stars are ejected from their galaxies or consumed by black holes. 32 Rs (1 × 10 21 a): Highest estimate of the time until all stars are ejected from galaxies or consumed by black holes. 10 30 and onward: quettasecond and beyond: Qs and on
24-hour digital clock in Miaoli HSR station. A public 24-hour clock in Curitiba, Brazil, with the hour hand on the outside and the minute hand on the inside.. A time of day is written in the 24-hour notation in the form hh:mm (for example 01:23) or hh:mm:ss (for example, 01:23:45), where hh (00 to 23) is the number of full hours that have passed since midnight, mm (00 to 59) is the number of ...
