Just proposing a possible structure

What is locale

Understanding and differentiating the two locales

Open point: proper naming for the 2 different locales.
Tmp names for this tmp page to be reused among this page:

• UAdmin-locale
• client-locale

Locale of the AdminCentral

AdminCentral's language setting is primarily used to define the language of User interface labels that the user of AdminCentral wants to see and work with, such as labels in the Action bar (English on the left, Korean on the right):

AdminCentral's time zone setting, on the other hand, has an effect on the content of – for instance – the Date field before any date is entered in it. The field shows a pseudo-placeholder text that changes according to the actual (user's) time zone setting, compare:

Surely, two different English-speaking editors, one working in London and the other one working in Berlin, will want to use their local times in many instances of such a field. In addition, the form of the timezone placeholder depends not only the time zone setting, but also on the language setting described just above. If the preferred working language of one of the editors is set to German, the hint will show MEZ (abbrev. of Mitteleuropäische Zeit) instead of CET (abbrev. of Central European Time).

Configuring the locales

With the configuration you define a set of possible languages plus a default language.

<We may or may not explaining here the config. depth. It also could be sufficient to link to the sections where it is already explained>

Setting the locale of the AdminCentral

When logged-in in the AdminCentral, users may set their locale via the Language and Time zone fields in the Edit user profile dialog. The language part of the locale setting will be reflected in the names of action menus, actions, buttons and labels throughout the AdminCentral provided the locale is one of the Available system languages (see further below) or it will fallback to English. 

To set a locale, open the pull down menu in the top right corner of the browser window and click the first row of the menu, titled Edit user profile if the current locale setting is English. On the Preferences tab:

• Choose a language in the Language field:
  
  With superuser role you may set language locales for other users, see Setting an editor's language preference.

• Choose a timezone in the Time zone field. 

The new locale will be applied the next time you log in into the AdminCentral.
