HTTP uses GMT [1,2] rather than UTC as timezone for timestamps. However, the Last-Modified header used UTC which confused at least wget. Before, UTC was used: $ wget --no-check-certificate -S --spider https://cb_pages_tests.localhost.mock.directory:4430/images/827679288a.jpg ... Last-Modified: Sun, 11 Sep 2022 08:37:42 UTC ... Last-modified header invalid -- time-stamp ignored. ... After, GMT is used: $ wget --no-check-certificate -S --spider https://cb_pages_tests.localhost.mock.directory:4430/images/827679288a.jpg ... Last-Modified: Sun, 11 Sep 2022 08:37:42 GMT ...
