		A countdown timer.
	</brief_description>
	<description>
		Counts down a specified interval and emits a signal on reaching 0. Can be set to repeat or "one-shot" mode.
		[b]Note:[/b] To create a one-shot timer without instantiating a node, use [method SceneTree.create_timer].

	<methods>
		<method name="is_stopped" qualifiers="const">
			<return type="bool" />
			<description>
				Returns [code]true[/code] if the timer is stopped.
			</description>
		</method>
		<method name="start">
			<return type="void" />
			<argument index="0" name="time_sec" type="float" default="-1" />
			<description>
				Starts the timer. Sets [code]wait_time[/code] to [code]time_sec[/code] if [code]time_sec &gt; 0[/code]. This also resets the remaining time to [code]wait_time[/code].
				[b]Note:[/b] this method will not resume a paused timer. See [member paused].

		</method>
		<method name="stop">
			<return type="void" />
			<description>
				Stops the timer.

			The timer's remaining time in seconds. Returns 0 if the timer is inactive.
			[b]Note:[/b] You cannot set this value. To change the timer's remaining time, use [method start].
