Hi! Thanks.
With fat files: # TZ=/usr/share/zoneinfo-test/Europe/Vienna date; TZ=/usr/share/zoneinfo-test/Europe/Vienna ./a.out Di. Feb. 11 09:47:29 CET 2020 local time: 09:47:29 UTC time: 08:47:29 Compared to before: # TZ=/usr/share/zoneinfo/Europe/Vienna date; TZ=/usr/share/zoneinfo/Europe/Vienna ./a.out Di. Feb. 11 09:47:44 CET 2020 local time: 10:47:44 UTC time: 08:47:44 So this seems to be the issue, and I'll raise a glib2 bug report now.
