Abstract

A timer service uses a single timer function to perform timing services for both relative and absolute timers. The first timers from a sorted array of absolute timers and relative timers are used in a function that will return when the earliest absolute timer expires or will timeout when the earliest relative timer expires. The timer function may be interrupted when a new timer is added to one of the arrays. The function will operate in a predictable and consistent manner, even when a system clock is adjusted.
