	  Enable use of __disable_irq() to disable Zero Latency IRQs to prevent
	  higher priority contexts (including ZLIs) that might preempt the
	  handler and call nrf_rtc_timer API from destroying the internal state
	  in nrf_rtc_timer.

	  When enabled, a function can be used to trigger RTC overflow and
	  effectively shift time into the future.
