[Buildroot] How to use the TZ selection ?

[Sagaert Johan]

 Dear Yann;

I had entered BR2_TARGET_LOCALTIME="Europe" ,
It did not resolve "Europe" and maybe that's why it created a symlink to a directory instead.
Perhaps it might be better to yield a build error in case the timezone could not be found.

Sagaert, All,

I've just tried it here with:
    BR2_TARGET_TZ_INFO=y
    BR2_TARGET_TZ_ZONELIST="default"
    BR2_TARGET_LOCALTIME="Europe/Paris"

And it gives me:
    $ stat -c '%N' target/etc/TZ
    'target/etc/TZ' -> '../usr/share/zoneinfo/uclibc/Europe/Paris'
    $ file target/etc/../usr/share/zoneinfo/uclibc/Europe/Paris
    target/etc/../usr/share/zoneinfo/uclibc/Europe/Paris: ASCII text
    $ cat target/etc/../usr/share/zoneinfo/uclibc/Europe/Paris
    # Europe/Paris
    CET-1CEST,M3.5.0,M10.5.0/3

So, this is indeed a symlink, but it points to a file, which contains a valid uClibc timezone spec.

What is your BR2_TARGET_LOCALTIME set to? This should be set to a valid location, usually a big city in an area.

The valid list is somewhere in the tzdata source tree (I'll leave as an exercise to you to find where! ;-) )
