One would think that a 12 billion year windowing
would be close enough. :-)

Not only that, but since by definition the Universe started at T=0, any
'sine wave' that starts at a positive zero-crossing is at any later time
indistinguishable from a real one that started at T=0.

Not if we were there the moment the later wave turned on. I heard that amateur
operators hate splatter. RC appears to be an exception, however.

See 'at any later time' in my text.
