# Gaussian Random Timer

*Part of the **Timers** category. Also documented in context in the [full Component Reference](/user-manual/component-reference/#gaussian-random-timer).*

![Gaussian Random Timer](/images/screenshots/timers/gauss_random_timer.png)

This timer pauses each thread request for a random amount of time, with most
of the time intervals occurring near a particular value.
The total delay is the sum of the Gaussian distributed value (with mean `0.0` and standard deviation `1.0`) times
the deviation value you specify, and the offset value.
Another way to explain it, in Gaussian Random Timer, the variation around constant offset has a Gaussian curve distribution.
