Timeout driver for event at absolute time
Timeout driver for generating event at absolute time, i.e. alarm at 12:00PM instead of alarm in 5 minutes.
This is the same concept as TIMER_ABSTIME in clock_nanosleep().
The purpose is to remove dependency on when
attach() is called, so the event occurs at correct time regardless of any latency in calling
This driver doesnt add any functionality over mbed-os library; it only skips the call to
Ticker::setup(), which just changes a relative time to absolute time.
example use here.
