| Title | IPMA - Avisos Meteorológicos em linha temporal |
| Against the capture before | the hash of the visible text differs from 11 Nov 2026, 06:25 UTC, but read by the archivist: same content. Every warning line and the list of regions read as at 06:25; only the hour labels of the page's time axis moved on ('06 12 18 00 ...' became '12 18 00 ...') as the day advanced. |
| Ignored when comparing | IPMA's pages print the time of the visit (for example '03h24m UTC:'), the warnings timeline prints the hour labels of its time axis, and the news list prints its dates in one of two forms depending on the load ('2026-11-10' or 'Tue Nov 10 08:00:00 UTC 2026'): all three are ignored when judging whether the page changed. |
