/**
* A coarse timer event which schedules far into the future. Use this
* when you need a coarse resolution, but the supported time span of
* #CoarseTimerEvent is not enough. For example, a good use case is
* timers which fire only every few minutes and do periodic cleanup.
*
* Right now, this is just an alias for #FineTimerEvent. This class
* supports arbitrary time spans, but uses a high-resolution timer.
* Eventually, we may turn this into a timer wheel with minute
* resolution.
