Timers are used for having actions performed repeatedly at a fixed interval (Eg every 100ms)
They should not be confused with Schedulers, which are for performing an action once at a given point of time in the future
Timers are typically low resolution (Compared to Schedulers), with maximum frequency currently being approximately every 10ms
