Is there a wait function to godot

You can’t just put it in a function like wait() and then call it.
Yield starts a co-routine. But you call it like a normal method. So it just starts the co-routine, but your _ready does not wait for completion of it.

This is a working code snippet:

extends Node

func _ready():
	print("{hour}:{second}".format(OS.get_datetime()))
	yield(wait(2), "completed")
	print("{hour}:{second}".format(OS.get_datetime()))

func wait(seconds):
	yield(get_tree().create_timer(seconds), "timeout")

To be honest I would not put it in a method. I would just use yield(get_tree().create_timer(seconds), "timeout") wherever you need it.
