Thanks. So I am marking this bug as invalid for tzdata, since tzdata
behaves correctly.
The remaining bug is that programs misbehave when TZ doesn't contain a
valid time zone. Which GUI programs misbehave or crash? I'll mark
coreutils (which ships the date command) as affected:
```
$ TZ=Canada/Ea
Thank you Benjamin (bdrung) -- the problem was that my
.bashrc/.bash_profile set TZ=Canada/Eastern, a legacy time zone name,
and that legacy name disappeared in Ubuntu 24.04.1. Its disappearance
caused many programs to silently misbehave, including both "date" and
the GUI. Setting TZ=America/Toro
** Summary changed:
- 24.04.1 tzdata wrong time zone, cannot reset, downgrade
+ 24.04.1 tzdata with unknown time zone quietly causes havoc
