What a difference a few decades make

I think the evidence of the effects of time is plain for all to see. However where is the actual evidence for the existence of time?

According to the modern physical view of wave function collapse, the theory of quantum decoherence, the quantum arrow of time is a consequence of the thermodynamic arrow of time. I'm none the wiser, but I can at least copy and paste like the rest of us.

This is a replacement for yesterday's original blip, which didn't survive. Hence some of the comments that don't match my sundial replacement. Apologies to all. Hopefully this one will stay and will be my entry for this weeks WBC challenge on the theme of TIME.
