No more invented name strings, but just the time offset inside <...> This seems to break musl. http://mm.icann.org/pipermail/tz-announce/2016-March/000036.html New zones Europe/Astrakhan and Europe/Ulyanovsk ... Asia/Barnaul ... As a trial of a new system that needs less information to be made up, the new zones use numeric time zone abbreviations like "+04" instead of invented abbreviations like "ASTT". I have tested with Openwrt trunk using musl (with Linux kernel 4.1) and older uClibc-based Openwrt CC15.05.1. The uClibc-based system uses the new zones ok, but the musl-based build behaves badly, as it defaults to GMT and shows the zonename as '+04>-4'. (This is when full zoneinfo files are not installed and just the TZ variable is used.) Examples at https://github.com/openwrt/luci/issues/675 (note: Openwrt patches musl to store TZ in /etc/TZ instead of an env variable, but that should have no impact in the displayed timezone.) Example with musl: old zone is ok: Europe/Helsinki root@OpenWrt:~# cat /etc/TZ EET-2EEST,M3.5.0/3,M10.5.0/4 root@OpenWrt:~# uptime 11:00:52 up 18:17, load average: 0.43, 0.13, 0.11 root@OpenWrt:~# date Wed Mar 30 11:00:55 EEST 2016 "new zone" is handle wrongly: Europe/Astrakhan root@OpenWrt:~# cat /etc/TZ <+04>-4 root@OpenWrt:~# uptime 08:02:52 up 18:19, load average: 0.17, 0.18, 0.13 root@OpenWrt:~# date Wed Mar 30 08:02:59 +04>-4 2016 (That should be Helsinki+1 (= +2 -DST) = 12:02:59)
