package timing

// NewRealtimeScheduler creates a scheduler backed by system real-time clock.
//
// It properly handles system suspend (sleep mode) and time adjustments. For periodic timers,
// it triggers immediately whenever time changes discontinuously. For one-shot timers
// (At and After), it will fire immediately if the time is skipped over
// the set trigger time, and will properly wait for it otherwise.
//
// This scheduler is only properly supported on Linux. On other systems,
// plain scheduler based on "time" package is returned.
//
// In order to clean up resources associated with it,
// remember to call Stop().
