Time/date format. The time and date format indicates the customary formatting for times and
dates in the region. The time and date format indicates whether dates are customarily
represented in the mm/dd/yy (month, day, year) or dd/mm/yy (day, month, year) format and
specifies what the days of the week and month are in a given language. For example, the
date January 10, 1996, is represented as 10.leden 1996 in Czechoslovakian and 10
janvier 1996 in French.
Because a locale describes cultural, customary, and regional differences in addition to
mechanical language differences, the directory data can both be translated into the specific
languages understood by users as well as be presented in a way that users in a given region
expect.
2. Identifying Supported Locales
When performing directory operations that require that a locale be specified, such as a search
operation, use a language tag or a collation order object identifier (OID).
A language tag is a string that begins with the two-character lowercase language code that
identifies the language, as defined in ISO Standard 639. If necessary to distinguish regional
differences in language, the language tag may also contain a two-character string for the
country code, as defined in ISO Standard 3166. The language code and country code are
separated by a hyphen. For example, the language tag used to identify the British English locale
is en-GB.
An object identifier (OID) is a decimal number used to uniquely identify an object, such as an
attribute or object class. The OIDs for searching or indexing an internationalized directory
identify specific collation orders supported by the Directory Server. For example, the OID
2.16.840.1.113730.3.3.2.17.1 identifies the Finnish collation order.
When performing an international search in the directory, use either the language tag or the OID
to identify the collation order to use. However, when setting up an international index, the OIDs
must be used. For more information on indexing, see Chapter 10, Managing Indexes.
Table D.1, “Supported Locales” lists each locale supported by Directory Server and identifies
the associated language tags and OIDs.
