so if a process is spawned and thent he TZ changes the process is stuck on the old TZ ? that seems totally broken John > With the current setup I simply added the following line to /etc/profile: > > [ -f /tmp/TZ ] && export TZ=$(cat /tmp/TZ) > > and now date returns the correct time and timezone. > > I however suspect that this fix doesn't work with processes started by procd, > actually I haven't had the time to check. > > If that is the case, would there be a way to populate the TZ env variable also > for those processes? > > Thank you, > > Gianluca > _______________________________________________ > openwrt-devel mailing list > openwrt-devel@lists.openwrt.org > https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel > _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
