/* This is the footertz string from `Europe/Paris` from tzdata 2020b. It’s
* used by GLib when the tzdata file was compiled with `zic -b slim`, which is
* the default in tzcode ≥2020b.
*
* The `M10.5.0` part indicates that the summer time end transition happens on
* the Sunday (`0`) in the last week (`5`) of October (`10`). That’s 6 days
* before the end of the month, and hence was triggering issue #2215.
