class FormatDate in Drupal 10

Converts date/datetime from one format to another.

Available configuration keys

• from_format: The source format string as accepted by \DateTime::createFromFormat.
• to_format: The destination format.
• from_timezone: String identifying the required source time zone, see DateTimePlus::__construct().
• to_timezone: String identifying the required destination time zone, see DateTimePlus::__construct().
• settings: keyed array of settings, see DateTimePlus::__construct().

Configuration keys from_timezone and to_timezone are both optional. Possible input variants:

• Both from_timezone and to_timezone are empty. Date will not be converted and be treated as date in default timezone.
• Only from_timezone is set. Date will be converted from timezone specified in from_timezone key to the default timezone.
• Only to_timezone is set. Date will be converted from the default timezone to the timezone specified in to_timezone key.
• Both from_timezone and to_timezone are set. Date will be converted from timezone specified in from_timezone key to the timezone specified in to_timezone key.

Examples:

Example usage for date only fields (DateTimeItemInterface::DATE_STORAGE_FORMAT):

process:
  field_date:
    plugin: format_date
    from_format: 'm/d/Y'
    to_format: 'Y-m-d'
    source: event_date

If the source value was '01/05/1955' the transformed value would be 1955-01-05.

Example usage for datetime fields (DateTimeItemInterface::DATETIME_STORAGE_FORMAT):

process:
  field_time:
    plugin: format_date
    from_format: 'm/d/Y H:i:s'
    to_format: 'Y-m-d\TH:i:s'
    source: event_time

If the source value was '01/05/1955 10:43:22' the transformed value would be 1955-01-05T10:43:22.

Example usage for datetime fields with a timezone and settings:

process:
  field_time:
    plugin: format_date
    from_format: 'Y-m-d\TH:i:sO'
    to_format: 'Y-m-d\TH:i:s'
    from_timezone: 'America/Managua'
    to_timezone: 'UTC'
    settings:
      validate_format: false
    source: event_time

If the source value was '2004-12-19T10:19:42-0600' the transformed value would be 2004-12-19T10:19:42. Set validate_format to false if your source value is '0000-00-00 00:00:00'.
