Package: wtmpdb Version: 0.75.0-6 Timestamps printed with --time-format=iso are not valid ISO 8601:
# wtmpdb last --time-format=iso | grep -wm1 boot s-reboot system boot 6.1.0-50-amd64 2026-07-17T18:15:14+0000 - still running This is invalid, because there's no colon in the timezone offset. In contrast, util-linux's last(1) did it right: # last --time-format=iso | grep -wm1 boot reboot system boot 6.1.0-50-amd64 2026-07-17T20:05:09+02:00 still running -- Jakub Wilk
