function _system_date_format_types_build

Builds and returns information about available date types.

Return value

An associative array of date type information keyed by name. Each date type information array has the following elements:

• type: The machine-readable name of the date type.
• title: The human-readable name of the date type.
• locked: A boolean indicating whether or not this date type should be configurable from the user interface.
• module: The name of the module that defined this format in its hook_date_format_types(). An empty string if the format was user-defined.
• is_new: A boolean indicating whether or not this date type is as of yet unsaved in the database.
