[Buildroot] [git commit] fs/skeleton: remove /etc/TZ

commit: http://git.buildroot.net/buildroot/commit/?id=5a61fbd82394f9bc9317535b717a2e1dd51dea7d
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Defaulting to UTC (which is what uClibc will default to when /etc/TZ is
missing) seems more sensible than US Mountain Time Zone in the default
rootfs skeleton.

And with glibc/eglibc?

As far as I understand it (e)glibc doesn't use /etc/TZ:

https://www.gnu.org/software/libc/manual/html_node/TZ-Variable.html

https://www.kernel.org/pub/linux/libs/uclibc/Glibc_vs_uClibc_Differences.txt

time functions
--------------
1) Leap seconds are not supported.
2) /etc/timezone and the whole zoneinfo directory tree are not supported.
   To set the timezone, set the TZ environment variable as specified in
   http://www.opengroup.org/onlinepubs/007904975/basedefs/xbd_chap08.html
   or you may also create an /etc/TZ file of a single line, ending with a
   newline, containing the TZ setting.  For example
   echo CST6CDT > /etc/TZ
3) Currently, locale specific eras and alternate digits are not supported.
   They are on my TODO list.

Ok. I know remember, on glibc I used /etc/localtime. I have patches
here that allow to configure the installation of a certain number of
zoneinfo files, and set a default zoneinfo, when glibc is used. I
should probably submit them someday.

Thanks for the clarification,

Thomas
