How can I use the Europe/Kyiv timezone in DDEV?

Question

I work with Drupal ^10 on ddev. Previously about year or so I faced issue, after some update, keeps throwing error. Notice: date_default_timezone_set(): Timezone ID 'Europe/Kyiv' is invalid in Drupal\system\TimeZoneResolver->setDefaultTimeZone() (line 54 of core/modules/system/src/TimeZoneResolver.php).

When i tried ddev config --timezone=Europe/Kyiv I got next error Warning: date_default_timezone_get(): Invalid date.timezone value 'Europe/Kyiv', we selected the timezone 'UTC' for now. in Drupal\Core\Datetime\DateFormatter->format() (line 105 of core/lib/Drupal/Core/Datetime/DateFormatter.php). Before that update everything was fine, and no errors with timezone. So if I understand correctly, there was some update with tzdata and timezone was changed to more correct version instead of Europe/Kiev => Europe/Kyiv, that was included in some ubuntu version, but ddev building images like before that update. Maybe someone configured ddev to fix such problem.

The problem here is that the Debian tzdata package has recently changed to use Europe/Kyiv instead of Europe/Kiev.

You can:

1. Use Europe/Kiev for now or
2. Add the tzdata package to get it updated with

ddev config --webimage-extra-packages=tzdata --dbimage-extra-packages=tzdata
ddev config --timezone=Europe/Kyiv
ddev restart

In the v1.23.0 release of DDEV it will be Europe/Kyiv by default (since it will pick up the latest tzdata).
