The current certificate is valid from Mon, 06 May 2024 07:58:01 GMT to Sun, 04 Aug 2024 07:58:00 GMT, it has been renewed today. Click on the padlock on the address bar and click your way through to see those dates. Renewal was probably automatic, in any case there was enough of a lapse for me to stumble across the error.
I don’t think 3650000 is a typo, that’s four zeros away from being a year.
Then where does the “365” come from? That’s some highly specific digits.
