Just write a small tool to map the local timezone from the IP lookup
to a timezone name (such as Europe/London) and write it to
/etc/timezone. You could do that with a short ifup script.

That said, for headless appliances working in UTC is absolutely fine,
and for user-facing devices it's perfectly acceptable to ask the user
what the timezone is, as your geo-IP lookup might be incorrect anyway.

I don't have option to add systemd.

Added alrady tzdata and all time zone folders exist.

The issue is that ntpdate returns time in UTC.

I found a way to get local time zone (by using ip lookup). Now i looking for a way to use it to update system time

If you're using systemd, you could use the timedatectl command:
https://linuxiac.com/how-to-set-timezone-and-sync-server-time-with-ntp-in-linux/

Otherwise, you can add the "tzdata" recipe to your image. It should
allow you to set the timezone that you want:

I made some progress...

It turns out that libquadmath is failing to build.

When I goto the `build/tmp/work/...../gcc-runtime/9.2.0-r0/gcc-9.2.0/build.arm-oe-linux-gnueabi.arm-oe-linux-gnueabi/arm-oe-linux-gnueabi/libquadmath` directory, the only files that are there are:

```

In the config.log, there are errors, some of which are expected, but still:

Have you seen something like this before?  I am not sure how to fix this...

Any help is greatly appreciated.

So, I built the latest poky and created the example recipe with the `DEPENDS` from my recipe and indeed, I see `libquadmath.so` in `sysroots-components/`.

I am really scratching my head now.  I must be missing something silly somewhere...

My build environment is running `zeus`  and the latest `poky` I grabbed is `honister`  Perhaps something changed that I am just overlooking somehow.

Thank you, Konrad.

I have tried both of the approaches (local.conf and gcc-runtime_%.bbappend/gcc_%.bbappend), still `libquadmath.so` is not being built.

I will keep fiddling but I think we are onto something.

The interesting thing I found is that `libquadmath.so` IS being built for the nativesdk but NOT when I add `DEPENDS = "virtual/${TARGET_PREFIX}compillerlibs"` to my recipe.

Perhaps, because `FORTRAN = ""` is in the gcc_%.bb, maybe that should be something less strict?

I might be screwing up my bbappend too...

My append is in `meta-mylayer/recipes-devtools/gcc/gcc-runtime_%.bbappend`

Which is mapped correctly to $BBFILES n my layers `layer.conf`

FORTRAN:forcevariable = ",fortran"

guess that will solve your issue without the need for a bbappend.
Just inject that line via distro or local.conf

Just use something like NTP to sync the local time. There's a number
of recipes that can do this, such as systemd/ntp/ntpdate.
