	that have occurred [see timerfd_create(2) for details]. 'settime flags' are

	flags in octal form been used to setup the timer [see timerfd_settime(2) for

	details]. 'it_value' is remaining time until the timer exiration.

	'it_interval' is the interval for the timer. Note the timer might be set up
