I regularly find myself on a zero manganese diet for hours at a time, and I've yet to experience immediate death, screaming in agony.
Furthermore we have lots of data on how well humans can tolerate extended low manganese regimens. The standard treatment course for TB in the 1950s resulted in humans having low manganese for 1-2 years. This was unpleasant, but not lethal.
Any google search on PAS and manganese will show that it eliminates manganese from the body by chelating it, and is therefore used for treating manganese toxicity.
I don't have a specific reference for manganese levels in people undergoing the old TB treatment. But I'm sure that it should exist somewhere.
Interesting, but why not use the timestamp baked into response headers? There's also domain.tld/cdn-cgi/trace for cloudflare. I don't know how cloudflare will take using that page for this though.
Cross-origin stuff doesn’t always let you get access to those headers and they may not always be there. Some web servers don’t put that there, some do. Some frameworks add them, some don’t.
Yes, many servers don’t expose Date to browsers (Access-Control-Expose-Headers), so you can’t read it cross-origin. Also, CDNs/proxies can cache or rewrite headers, my goal was a boring, local /time on the same gateway the tech is testing. Another thing was that Date is seconds-resolution, I want ms and a stable JSON shape. I have found Cloudflare trace to be handy in past, but it’s not my box, it may rate-limit, and adds an extra network hop. For the core question "Is it me or the edge box" I wanted the box itself to answer.
Ps: the heating is increasingly heat pump based instead of resistive.
