Format a date with the given configured format or a custom format string.

Drupal allows administrators to select formatting strings for 'small', 'medium' and 'large' date formats. This function can handle these formats, as well as any custom format.

Parameters

$timestamp: The exact date to format, as a UNIX timestamp.

$type: The format to use. Can be "small", "medium" or "large" for the preconfigured date formats. If "custom" is specified, then $format is required as well.

$format: A PHP date format string as required by date(). A backslash should be used before a character to avoid interpreting the character as part of a date format.

$timezone: Time zone offset in seconds; if omitted, the user's time zone is used.

$langcode: Optional language code to translate to a language other than what is used to display the page.

Return value

A translated date string in the requested format.
