Actually you first need to install the ‘tzdata’ package (which I just
added yesterday!).  Then you must set the TZDIR environment variable to
point to it, like this:

  export TZDIR=$HOME/.guix-profile/share/zoneinfo

The C library (the one from Guix) will then get timezone info from there.

This is actually unrelated but yes, this one’s fixed too.

What matters most is what’s in your profile.  I just run ‘guix package --upgrade’,
which atomically upgrades everything that’s installed in your profile
(so you get the new Coreutils, and everything linked against the new libc.)

HTH!
