Me, before doing the PR: … oh, must fix the timestamp in that JSON file, it's from 2 days ago…

CI: Oh, the timestamp is in the future…

🤷

Hah! I worried that CI could be running in some US timezone, but docs day it's UTC, and indeed your comment was on Monday the 23rd at 23:45 UTC I think?

[mmuman]

Probably, we're UTC+2 here…

[Wilm0r]

I guess I could add a timezone tag in the error message, or for "comfort", maybe use Australian timezone :)

[mmuman]

It's fine as-is really.
