Windows Clock (known as Clock & Alarms on Pocket PC 2000, [2] Alarms on Windows 8.1, and, until July 2022, Alarms & Clock on Windows 10) is a time management app for Microsoft Windows, with five key features: alarms, world clocks, timers, a stopwatch, and focus sessions. The features are listed on a sidebar.
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 ...
A time bomb's timing mechanism may be professionally manufactured either separately or as part of the device, or it may be improvised from an ordinary household timer such as a wind-up alarm clock, wrist watch, digital kitchen timer, or notebook computer. The timer can be programmed to count up or count down (usually the latter; as the bomb ...

Most of the materials required can be easily obtained. The bomb can be triggered using a simple electronic device such as a digital watch, garage door opener, cell phone, pager, kitchen timer, or alarm clock. [1] [3] The power of the explosion depends on the size of the pressure cooker and the amount and type of explosives used. [4]
A typical kitchen timer. 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.
Section 8.1 of the Texas Instruments NE555 datasheet [1] states a value of 100 kHz, and their website shows a value of 100 kHz in timer comparison tables. Signetics App Note 170 states that most devices will oscillate up to 1 MHz; however, when considering temperature stability, it should be limited to about 500 kHz. [ 2 ]
