NAME

       "IO::Async::Timer::Absolute" - event callback at a fixed future time

SYNOPSIS

	use IO::Async::Timer::Absolute;

	use POSIX qw( mktime );

	use IO::Async::Loop;
	my $loop = IO::Async::Loop->new;

	my @time = gmtime;

	my $timer = IO::Async::Timer::Absolute->new(
	   time => mktime( 0, 0, 0, $time[4]+1, $time[5], $time[6] ),

	   on_expire => sub {
	      print "It's midnight
";
	      $loop->stop;
	   },
	);

	$loop->add( $timer );

	$loop->run;

DESCRIPTION

       This subclass of IO::Async::Timer implements one-shot events at a fixed time in the future. The object waits for a given timestamp, and
       invokes its callback at that point in the future.

       For a "Timer" object that waits for a delay relative to the time it is started, see instead IO::Async::Timer::Countdown.

EVENTS

       The following events are invoked, either using subclass methods or CODE references in parameters:

   on_expire
       Invoked when the timer expires.

PARAMETERS

       The following named parameters may be passed to "new" or "configure":

       on_expire => CODE
	       CODE reference for the "on_expire" event.

       time => NUM
	       The epoch time at which the timer will expire.

       Once constructed, the timer object will need to be added to the "Loop" before it will work.

       Unlike other timers, it does not make sense to "start" this object, because its expiry time is absolute, and not relative to the time it is
       started.
