Cldr Dates Times v0.1.2 Cldr.Time View Source

Provides an API for the localization and formatting of a Time struct or any map with the keys :hour, :minute, :second and optionlly :microsecond.

CLDR provides standard format strings for Time which are reresented by the names :short, :medium, :long and :full. This allows for locale-independent formatting since each locale may define the underlying format string as appropriate.

Examples

iex> Cldr.Time.to_string ~T[07:35:13.215217]
{:ok, "7:35:13 AM"}

iex> Cldr.Time.to_string ~T[07:35:13.215217], format: :short
{:ok, "7:35 AM"}
