The first use of a time bomb in software may have been in 1979 with the Scribe markup language and word processing system, developed by Brian Reid.Reid sold Scribe to a software company called Unilogic (later renamed Scribe Systems [2]), and agreed to insert a set of time-dependent functions (called "time bombs") that would deactivate freely copied versions of the program after a 90-day ...
The ticking time bomb scenario is a thought experiment that has been used in the ethics debate over whether interrogational torture can ever be justified. The scenario can be formulated as follows: The scenario can be formulated as follows:
Pencil detonators are colour-coded to indicate the nominal time delay, which can range from 10 minutes through to 24 hours. No. 10 delays were normally issued in a tin of 5, all of the same delay, while L-delays were issued in a larger tin which included a mixture of different delays to suit a variety of operations. The time delay of a No. 10 ...
Many computer systems measure time and date using Unix time, an international standard for digital timekeeping. Unix time is defined as the number of seconds elapsed since 00:00:00 UTC on 1 January 1970 (an arbitrarily chosen time based on the creation of the first Unix system), which has been dubbed the Unix epoch.

In the context of a rocket launch, the "L minus Time" is the physical time before launch, e.g. "L minus 3 minutes and 40 seconds". "T minus Time" is a system to mark points at which actions necessary for the launch are planned - this time stops and starts as various hold points are entered, and so doesn't show the actual time to launch.
The Cold War ended in 1991, but the looming threat of nuclear attack lives on with more than 14,900 nuclear weapons wielded by nine nations.. A terrorist-caused nuclear detonation is one of 15 ...
"Mike", codename for the bomb, released energy equal to around 10 megatons — or 10 million tons of TNT. [13] In 1961, the Tsar bomb was exploded by the Soviet Union, producing an explosion with a mass of 50 megatons— which was about 1,500 times more than the combined force of the atomic bombs fired on Hiroshima and Nagasaki.

A timer or countdown timer is a type of clock that starts from a specified time duration and stops upon reaching 00:00. An example of a simple timer is an hourglass. Commonly, a timer triggers an alarm when it ends. A timer can be implemented through hardware or software.
