-			The wait time in seconds.
-			[b]Note:[/b] Timers can only emit once per rendered frame at most (or once per physics frame if [member process_callback] is [constant TIMER_PROCESS_PHYSICS]). This means very low wait times (lower than 0.05 seconds) will behave in significantly different ways depending on the rendered framerate. For very low wait times, it is recommended to use a process loop in a script instead of using a Timer node. Timers are affected by [member Engine.time_scale], a higher scale means quicker timeouts, and vice versa.
+			The time required for the timer to end, in seconds. This property can also be set every time [method start] is called.
+			[b]Note:[/b] Timers can only process once per physics or process frame (depending on the [member process_callback]). An unstable framerate may cause the timer to end inconsistently, which is especially noticeable if the wait time is lower than roughly [code]0.05[/code] seconds. For very short timers, it is recommended to write your own code instead of using a [Timer] node. Timers are also affected by [member Engine.time_scale].
