WordPress Speed Up Service | WordPress Website Maintenance Packages How will changing Timezone affect existing posts?, by azurajia Hi there, Say, I have this post published at 4am, on 28 Oct 2017, with my timezone set to UTC+0. If I later change my timezone to UTC+8, and edit this post and update it, leave the publish time unchanged, does that mean the publish time in fact WILL CHANGE to 4am 1 Jan 2011 in UTC+8 timezone (so that’s in fact 8pm 27 Oct 2017 in UTC+0)? Or maybe WordPress will memorize the timezone I set when first publishing the post (UTC+0)? Or maybe it only memories the time and date I put in there, and processes it in a irrelevant way to timezone setting or something? Published date seems by default always display 28 Oct 2017 though, no matter to me or to visitors, no matter what timezone I change my WordPress into or what timezone my visitors are in. (I changed the timezone of my computer and browsered as a visitor, the date didn’t appear to change. What date does u guys see?) I’m just a bit confused and curious about how switching timezone will affect existing posts in a deeper level… if there is any. As far as I know, switching timezone can affect scheduled publish, but will it effect existing posts in some way, either to the owner of the site or to the visitors? Thanks!
