"Nine hours?"

I don't know why you're questioning that.

I said "I'm seeing roughly 9 hours difference" [my added emphasis]. On PM I see: "Jul 31, 2018 at 04:49 AEST". On "blogs" I see: "July 30, 2018 7:40 PM". Without knowing the timezone of "blogs", there's no way of knowing what the real difference is.

"Nah, more like ten minutes. Blogs.perl.org first, then dumbed down the HTML for Perlmonks."

++ Thanks for the clarification.
