2. Programmable interval timer - Wikipedia

   en.wikipedia.org/wiki/Programmable_Interval_Timer

   Timer 0 is used by Microsoft Windows (uniprocessor) and Linux as a system timer, timer 1 was historically used for dynamic random access memory refreshes and timer 2 for the PC speaker. [ 2 ] The LAPIC in newer Intel systems offers a higher-resolution (one microsecond) timer. [ 3 ]

3. High Precision Event Timer - Wikipedia

   en.wikipedia.org/wiki/High_Precision_Event_Timer

   The High Precision Event Timer (HPET) is a hardware timer available in modern x86-compatible personal computers. Compared to older types of timers available in the x86 architecture, HPET allows more efficient processing of highly timing-sensitive applications, such as multimedia playback and OS task switching .

4. Watchdog timer - Wikipedia

   en.wikipedia.org/wiki/Watchdog_timer

   A watchdog timer (WDT, or simply a watchdog), sometimes called a computer operating properly timer (COP timer), [1] is an electronic or software timer that is used to detect and recover from computer malfunctions. Watchdog timers are widely used in computers to facilitate automatic correction of temporary hardware faults, and to prevent errant ...

5. Intel 8253 - Wikipedia

   en.wikipedia.org/wiki/Intel_8253

   Intel C8253 Intel 8253 programmable interval timer. Intel 8254 has the same pinout. The Intel 8253 and 8254 are programmable interval timers (PITs), which perform timing and counting functions using three 16-bit counters. [1] The 825x family was primarily designed for the Intel 8080/8085-processors, but were later used in x86 compatible systems.

6. Epoch (computing) - Wikipedia

   en.wikipedia.org/wiki/Epoch_(computing)

   Software timekeeping systems vary widely in the resolution of time measurement; some systems may use time units as large as a day, while others may use nanoseconds.For example, for an epoch date of midnight UTC (00:00) on 1 January 1900, and a time unit of a second, the time of the midnight (24:00) between 1 January 1900 and 2 January 1900 is represented by the number 86400, the number of ...

7. Sleep (system call) - Wikipedia

   en.wikipedia.org/wiki/Sleep_(system_call)

   On Windows, the Sleep() function takes a single parameter of the number of milliseconds to sleep. The Sleep() function is included in kernel32.dll. [1]The Sleep() function has a resolution no higher than the current timer resolution, typically 16ms but at minimum 1ms, adjustable via the timeBeginPeriod() family of "media timer" APIs.

8. cron - Wikipedia

   en.wikipedia.org/wiki/Cron

   Note: On some systems it is also possible to specify */n to run for every n-th interval of time. Also, specifying multiple specific time intervals can be done with commas (e.g., 1,2,3). The line below would output "hello world" to the command line every 5th minute of every first, second and third hour (i.e., 01:00, 01:05, 01:10, up until 03:55).

9. Intervalometer - Wikipedia

   en.wikipedia.org/wiki/Intervalometer

   Photographers use intervalometers to trigger exposures.Photographers often do this for a time-lapse series, or to take or begin taking picture after a set delay.. Examples of intervalometer use in aerial photography include delaying the start of picture taking by an unattended camera until some time after takeoff and separating multiple exposures in time, and thus distance as the vehicle ...
