Package: tzdata Version: 2017b-0+deb8u1 Severity: normal Dear Maintainer,
After upgrading tzdata from 2016j-0+deb8u1 to 2017a-0+deb8u1 the timezone abbreviation for the local time stopped showing on date and on our email timestamps. Still happening on 2017b-0+deb8u1 Until version 2016j-0+deb8u1, the timezone abbreviation (for example BRT, BRST) was shown. After the upgrade, the abbreviation was replaced by the time offset (-03, -02) Downgrading the tzdata package alone reverts to the working situation: root@gronholm:~# date Mon Apr 17 15:23:30 -03 2017 root@gronholm:~# date +%Z -03 root@gronholm:~# apt-get install tzdata=2016j-0+deb8u1 Reading package lists...
