| 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. |
