Return the preferred time format for a locale.

Arguments

• language_tag is any language tag returned by Cldr.Locale.new/2 or any locale_name returned by Cldr.known_locale_names/1

Returns

• The hour format as an atom to be used for localization purposes. The return value is used as a function name in Cldr.DateTime.Formatter

Notes

• The hc key of the u extension is honoured and will override the default preferences for a locale or territory. See the last example below.

• Different locales and territories present the hour of day in different ways. These are represented in Cldr.DateTime.Formatter in the following way:

Examples

iex> Cldr.Time.hour_format_from_locale "en-AU"
:h12

iex> Cldr.Time.hour_format_from_locale "fr"
:h23

iex> Cldr.Time.hour_format_from_locale "fr-u-hc-h12"
:h12
