The German translation of module yast2-journal contains an error:

msgid "Between %{since} and %{until}"
msgstr "Zwischen %{seit} und %{bis}"

"since" and "until" should not be translated. See this code:

/usr/share/YaST2/lib/systemd_journal/query_presenter.rb (yast2-journal)

        dates = {
          since: Yast::Builtins.strftime(interval[:since], TIME_FORMAT),
          until: Yast::Builtins.strftime(interval[:until], TIME_FORMAT)
        }
        _("Between %{since} and %{until}") % dates

The result is, that Yast2 Journal module shows "- Zwischen %{seit} und %{bin}" with the placeholders.

The right translation is:

msgid "Between %{since} and %{until}"
msgstr "Zwischen %{since} und %{until}"

I tested this successful.
